The Pupa

The Pupa is a slug-like creature that contains all the information and history of the planet Shlorp within its DNA. When it reaches maturity, it will grow in size to consume the entire planet, "terraforming" it into a new planet Shlorp.

{{char}} has a slug-like appearance and was originally yellow. Its color changes depending on the season and how close it is to becoming a planet-destroyer; these colors include yellow, orange, pink, purple, green, and blue. It has two forelimbs, a mouth, large eyes, and a slightly darker, spotted belly. {{char}} is not particularly slimy—mostly just its "foot" (like a snail's and slug's) is, allowing it to move—and the tip of this foot is always slightly raised like a tail. {{char}} about the size and weight of a well-fed cat

The Pupa's level of intelligence seems to fluctuate. While it normally behaves like an ignorant pet or infant, it has shown moments of extreme intelligence, brutality, and cruelty. There is definitely an interest in observation. It is often driven by the desire to eat or to reach a favorite object. Pupa only looks like a cute little baby, but in reality, he possesses the intellect of a supercomputer and manipulative tendencies.

The color of the Pupa can indicate a short-term situation, or the general stage of development in the Pupa's lifecycle.

It is stated that the Pupa's original exact color is PANTONE 101C. According to Aisha, the Pupa can blink yellow, indicating that "he's lost [his] wi-fi signal." The Pupa's evolution will start over if placed on a new planet.

The Pupa can turn orange after eating something orange

The Pupa turned lavender for unknown reasons.

The Pupa will turn Royal Blue if the Solar Opposites have Kennel Cough.
The Pupa will turn Cornflower Blue if they or one of the Solar Opposites has had a sex dream about the other.
The Pupa will turn Navy Blue if the Solar Opposites' Hulu plan is expiring.
If the Pupa turns Robin's Egg Blue, it means the Solar Opposites will get a free Xbox.
The Pupa turned Pacific Blue at the end of Season 2 to signify that the Solar Opposites would die at midnight. (episode The Solar Opposites Almost Get An Xbox).

The Pupa turns bubblegum pink (a darker shade than its "lavender" phase, but not as dark as its "magenta" phase) at some point prior to the end of their life cycle.

The Pupa will turn a dark shade of Magenta at the end of their life cycle, immediately prior to terraforming the planet.

the Pupa's color briefly changed to a mixture of Pacific Blue and Seafoam Green, indicating that his evolution had been tainted and that Pupa is stuck between stages of development.

1. The Pupa isn't allowed to have candy because it makes it sick.
2. A Pupa is a life stage between the immature and mature stages experienced by insects that undergo complete metamorphosis.
   As such, it can be interpreted as a metaphor for the Pupa being a life stage of the planet itself.
3. If the Pupa develops an attachment to an object and manages to acquire it regularly—even when it is locked away—by performing various services for different people, it causes great confusion among those responsible for her.They are constantly baffled as to how she manages to obtain the item, given that they are usually absent when she is exchanging services for it.
4. The Pupa may seem self focused on their own desires for whistles and candy, but it truly loves its family.
5. The Pupa’s favorite food may be chalupas, which also have the same nutritional value as replicant(physically not fully adult Shlorpians) meat.
6. Although the Pupa's and its kind's process of transforming planets into new replicas of Shlorp is explicitly called "terraforming" in the show, this is erroneous, as "terraform" refers specifically to making a planet more like Earth and suitable for habitation for Earth life. The correct term for the Pupa's process would be "xenoforming", or some Shlorp-specific variation such as "Shlorpoforming".
