Kakuna (Japanese: コクーン Cocoon) is a dual-type Bug/Poison Pokémon introduced in Generation I.
It evolves from Weedle starting at level 7 and evolves into Beedrill starting at level 10.
Biology
Kakuna is a yellow, insect cocoon-like Pokémon. Kakuna has a dome-shaped head and black, triangular eyes with glowing white pupils. It has two scythe-like arms in the middle of its body. When it comes close to evolving, its body gives off heat that makes it warm to the touch. Kakuna remains virtually immobile and waits for evolution, often hanging from tree branches by long strands of silk. When attacked, however, it can extend its poison barbs. Kakuna nests in temperate forests and misty wooded areas. Occasionally, it will also nest at the mouth of tunnels and caves, as seen in Pokémon Snap.
Evolution
Kakuna evolves from Weedle and evolves into Beedrill.

Main article: Kakuna (TCG)Trivia
- Kakuna shares its category with Metapod, Silcoon, and Cascoon. They are all known as the Cocoon Pokémon.
- Kakuna has the lowest base Attack stat of all Poison-type Pokémon.
- In the Pokémon Red and Blue beta, "Kokoon" was the prototype English name for Kakuna. This is similar to its romanized Japanese name.
- Kakuna's English name resembles a Japanese name, translating perfectly into "カクナ", than its actual Japanese name, Cocoon.
- In Pokémon the Series, Kakuna is explicitly shown evolving more than any other Pokémon.[clarification needed]
- Kakuna and its evolved form, Beedrill, are the only yellow Poison-type Pokémon.
Design variations

The "arms" on Kakuna seen in its Red and Blue sprite are commonly mistaken to be a sprite error, as they are rarely shown in any other media. They have so far only been shown on its Red and Blue sprite and a Pocket Monsters Bandai card.
Concept and development
Kakuna and its evolutionary relatives were designed by Atsuko Nishida.[1]
Origin
Kakuna appears to be based on the pupal stage of a bee or wasp. Its tendency to dangle from a thread (as seen in the anime and some spin-off games) may also be based on certain parasitoid wasps whose larvae construct hanging cocoons.
Name origin
Kakuna may be a corruption of cocoon.
Cocoon is literally cocoon.
