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.
In the Pokémon Red and Blue beta, "Kokoon" was the prototype English name for Kakuna. This is the same as its romanized Japanese name.
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.
