Hello there! Welcome to Professor Jacob’s twelfth lesson on Pokémon biology. We wrap up Caterpie's evolutionary line today as we discuss Butterfree: the Butterfly Pokémon. Although it may not look like it, we learn that our new class pet, Matterpie (who is now Mutterfree the Butterfree), can actually be quite deadly. Therefore, Prof. Jacob has opted to not bring Matterpie into the classroom today. "But what makes Butterfree so dangerous?" you might ask, young student. Well, if we told you here in the description, it would defeat the purpose of the lesson. Oh, and there's another pop quiz today... shocker!
