Kakuna

Kakuna appeared in 1996 video game called Pokémon Red & Green. Kakuna is a Cocoon Pokémon. Kakuna appears motionless from the outside, but inside its shell, it's busily preparing to evolve. Sometimes the shell heats up from this activity.

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 on 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.
