Traits

Form Change (Limited)

Category: Exclusives
Species: Terralien

A transformation that affects the entire body, allowing a Terralien to shape-shift into an entirely new, different form.


  • This trait allows for the addition of new colors without the need for an item. Any new colors can only be applied to the area affected by the trait — adding new colors elsewhere on the body requires a Betta Brush.
  • All forms present must be similar to the base design. This includes similar visor contents — only slight variations of visor contents are permitted. For example, if the main body’s visor contains an insect, all alternate form's visors must also contain insects.
  • The Color Shift and Morphing traits are NOT required for alternate forms.
  • Forms can have different traits from one another so long the base design remains recognizable. Adding traits not present on the original design requires the appropriate items for each trait.

This trait is applicable to the following subtypes for free when submitting a new design:

  • Synthetic
  • Edible
  • Planetary

Elemental (Limited)

Category: Exclusives
Species: Terralien

Parts of a Terralien’s body that consists of elemental matter, such as fire, water, ice, or smoke. 


  • This trait allows for the addition of new colors without the need for an item. Any new colors can only be applied to the area affected by the trait — adding new colors elsewhere on the body requires a Betta Brush.
  • This trait only applies to the body. For example, if a Terralien has an arm made of water, the Elemental trait is required, but if a Terralien has disconnected water droplets floating around their body, the Holograms trait is required instead.
  • Can only be applied to 50% or less of any non-limited subtype’s design. This coverage also combines with other inorganic traits such as Material Parts and Terrarium Body -- 50% must remain regular organic body material.
  • CANNOT resemble Material Parts

This trait is applicable to the following subtypes for free when submitting a new design:

  • Synthetic
  • Edible

Visor Mouth (Modified)

Category: Subtype
Species: Terralien

Visor contents that part into a mouth-like shape.


  • When adding this trait via a design update, its color must be derived from the visor’s existing glass color. Adding additional colors requires an Inky Leaf .
  • CANNOT  be paired with the Visor Eye trait.
  • Must clearly be made of the same contents within the visor. 

This trait is applicable to the following subtypes for free when submitting a new design:

  • Synthetic
  • Edible
  • Microbe

Aquatic Tail (Basic)

Category: Subtype
Species: Terralien

A tail resembling that of an aquatic animal.


  • When adding this trait via a design update, its color must be derived from the Terralien’s pre-existing body colors. Adding new colors requires the use of a Betta Brush.
  • Does NOT apply to simple tapered tails, like those found on Otters.
  • Does NOT require the Fins/Webbing trait, so long as any fins or webbing are located only on the tail. If any are present on the body, the Fins/Webbing trait is required.

This trait is applicable to the following subtypes for free when submitting a new design:

  • Amphibian
  • Aquatic
  • Synthetic
  • Edible

A Sunken Tail is required to apply this trait to the following subtypes, or to pre-existing designs:

  • Sprout
  • Bug
  • Beast
  • Reptilian
  • Marine
  • Microbe
  • Fossil
  • Planetary

Visor Eye (Modified)

Category: Subtype
Species: Terralien

Visor contents that mimic an eye.


  • If applied to the microbe subtype, visor eyes are required to consist of the same microbes within the visor.
    • The Screen Visor trait is required for eyes that are not made of the visor’s contents.
  • CANNOT  be paired with Visor Mouth.

This trait can ONLY be applied to the Synthetic and Microbe subtypes. 

Plant Tail (Basic)

Category: Subtype
Species: Terralien

A tail made of plant or fungal matter.


  • When adding this trait via a design update, its color must be derived from the Terralien’s pre-existing body colors. Adding new colors requires the use of a Betta Brush
  • Plant Tails can consist of tentacle-like vines, but cannot mimic marine tentacles without both the Aquatic Tail and Tentacle traits.
  • Does NOT grant the Plant Growth trait. 
  • The Plant Growth trait is required if smaller plants are sprouting from the Plant Tail itself.
  • Can be made up of fruits or vegetables, so long as the plant the fruit/vegetable is growing from is present.
  • CANNOT mimic Object Tail without both traits being applied. For example, fruits or vegetables that are not growing from a plant fall under Object Tail and Plant Tail.

This trait can ONLY be applied to the Sprout, Synthetic, and Edible subtype. To apply this trait to pre-existing Sprout, Synthetic, or Edible Terraliens, an Oddity Tail is required.

Mandibles (Basic)

Category: Subtype
Species: Terralien

Insect-like mouth pieces or pincers.


  • When adding this trait via a design update, its color must be derived from the Terralien’s pre-existing body colors. Adding new colors requires the use of a Betta Brush.
  • CANNOT be applied to the visor. Mandible-like protrusions from the visor require the Shaped Visor trait.
  • Can be shiny, but cannot mimic Iridescence, Material Parts or Metallic Shimmer without those traits being applied as well.
  • Can be located anywhere on the body. 

This trait is applicable to the following subtypes for free when submitting a new design:

  • Bug
  • Synthetic
  • Edible

A Pincher Potion is required to apply this trait to the following subtypes, or to pre-existing designs:

  • Amphibian
  • Sprout
  • Beast
  • Reptilian
  • Marine
  • Microbe
  • Fossil
  • Planetary

Microbe Tail (Modified)

Category: Subtype
Species: Terralien (Microbe subtype)

A transparent tail consisting of the same contents as a Microbe Terralien’s visor.


  • When adding this trait via a design update, its color must be derived from the visor and visor content's existing colors. Adding additional colors requires a Betta Brush.
  • Must contain the same kind of microbes as the visor.
  • Grants the Transparency trait.


This trait can ONLY be applied to the Microbe subtype. To apply this trait to pre-existing Microbe Terraliens, an Oddity Tail is required.

Fossilized Parts (Modified)

Category: Subtype
Species: Terralien (Fossil subtype)

Growths of stones, crystals, bones, or gems that may or may not replace parts of a Terralien’s body.


  • Does not allow for growths made of metal or man-made materals. Metal or man-made material growths require the Material Parts trait.
  • Can be shiny, but cannot mimic Glitter, Iridescence, Material Parts or Metallic Shimmer without said traits also being applied.
  • CANNOT resemble an Exoskeleton without both traits being applied.
  • CANNOT appear as processed or smooth gemstones.

  • The Exoskeleton trait is required for Arthropod Tails with an exoskeleton.

This trait is applicable to the following subtypes for free when submitting a new design:

  • Bug
  • Synthetic
  • Edible

A Skittering Tail is required to apply this trait to the following subtypes, or to pre-existing designs:

Illegal (Illegal)

Category: Illegal

Terraliens with this tag have an aspect on their design that can no longer be replicated, which is specified in the trait notes.
Please keep in mind there may be other Terraliens with illegal design aspects that do not have this trait listed.

If a redesign is submitted, Terraliens with this tag are required to have any illegal aspects fixed, with the exception of illegal screenvisors, which DO NOT require changing,
