Hello there! Welcome to Professor Jacob’s fourteenth lesson on Pokémon biology. We continue Weedle's evolutionary line by discussing the amazingly boring Cocoon Pokémon: Kakuna. Like Metapod, this yellow lump essentially just sits there as the metamorphosis continues within the  shell. However, the shell can get very hot while preparing to evolve, so please do not use Kakuna for a game of hot potato. And don't forget, students, there is another pop quiz today!
