Kakuna

Kakuna (コクーン Cocoon) is a /-type Pokémon. It evolves from Weedle starting at level 7 and evolves into Beedrill at level 10.

Appearance
Kakuna is an insect-like Pokémon with an appearance similar to that of a yellow chrysalis. As a chrysalis, the interior of Kakuna's very hard shell is unseen, with no limbs or other features being shown. Only Kakuna's eyes, jet black in color, are visible from the shell, which are somewhat large in proportion to its body. In Pokémon Red and Blue Versions, Kakuna had arm-like limbs, which were never seen afterwards.

Special abilities
All Kakuna have the ability Shed Skin, which allows for a 1/3 chance that a status effect will be dropped each turn. As Kakuna are inside of a shell, they have little or no movement and almost no offensive capabilities. As a defensive measure, they can harden their shells against an attacker and may even be able to use Poison Sting.

In the anime series
Kakuna first appeared in the anime series in the episode Challenge of the Samurai, where they were being protected by their evolved form, Beedrill. Kakuna have made various minor appearances throughout the series in a similar fashion to that of their debut appearance.

Origins
Kakuna's English and Japanese names are based off of the word "cocoon", though the English name is more of a distorted version of the word. This applies for the species of Kakuna being a cocoon.
