Cascoon is a round, cocoon-like Pokémon. It is covered in purple silk, except for two holes where its red eyes are visible. The soft silk hardens into a tough cocoon that is able to endure attacks, and Cascoon will not move even when it is attacked. However, it never forgets the pain it endures and seeks revenge upon evolution. It lives in forests, where it hides underneath large leaves and inside the gaps of tree branches. Additionally, it camouflages itself by attaching dead leaves to its body. As its cells create energy for evolution, the inside of the cocoon becomes hot. Cracks start to form in its casing when evolution is near.
In A Corphish out of Water, Jessie's Wurmple evolved into a Cascoon, but she thought it was a Silcoon. As a result, James and Meowth were left worried about Jessie's rage when Cascoon evolved into a Dustox. Fortunately, Jessie was ultimately not disappointed when Cascoon did indeed evolve.

In Best Friend...Worst Nightmare!, Goh's three Wurmple all evolved into Cascoon. They reappeared in JN015 and JN023, the latter in which they all evolved into Dustox.
Cascoon makes its protective cocoon by wrapping its body entirely with a fine silk from its mouth. Once the silk goes around its body, it hardens. This Pokémon prepares for its evolution inside the cocoon.
If it is attacked, Cascoon remains motionless however badly it may be hurt. It does so because if it were to move, its body would be weak upon evolution. This Pokémon will also not forget the pain it endured.
To avoid detection by its enemies, it hides motionlessly beneath large leaves and in the gaps of branches. It also attaches dead leaves to its body for camouflage.

They also share the same base stat total, learnset, Ability, and EV yield.
This ties them as the evolved Pokémon with the lowest base stat total.

Cascoon, along with Silcoon, can be seen without the limb protrusions on its body in the anime, all core series games from X and Y onward, and occasionally in HeartGold and SoulSilver.
However, James's Pokémon trivia cards showed that Silcoon and Cascoon indeed have those limbs.
Cascoon is the only Bug-type cocoon-based Pokémon whose Defense stat does not decrease upon evolution.
Cascoon is the only Pokémon found in a Friend Safari that is not its own type; it is found in the Poison-type Friend Safari even though Cascoon is pure Bug. However, it evolves into the Poison-type Dustox.
Cascoon may be a combination of cask (a container, often cylindrical) or casca (Portuguese for shell), and cocoon. It could also derive from cast, a shell meant for immobilizing part of the body or the method of creating said shell.
Mayuld is a combination of 繭 mayu (cocoon) and shield.
