Here's the move list.
While most Pokémon belong to a single
     category or type, Weedle feature the
     combined characteristics of a Bug-type and
     Poison-type Pokémon. Weedle have only two
     attack strategies, but their sting is poisonous
     and their String-Shot attack can temporarily
     reduce an enemy's speed. Weedle evolve into
     Kakuna and eventually into Beedrill. Found in
     both versions, these Pokémon are rare in the
     Blue version.
