#266
Cocoon Pokémon
Silcoon is a Bug-type Pokémon, No. 266 in the National Pokédex, introduced in Generation 3 (Hoenn region).
« Wraps itself in thin strings of silk while it stores energy for evolution. It can't extend its limbs and its movement is slow, but its eyes keep a sharp lookout—Silcoon is always on guard. »
Silcoon is a cocoon tied to branches, almost fully wrapped in white silk. Two small holes show red eyes, partly hidden by a rough silk fringe.
Its hard shell repels attacks. Dew and rain feed it. In forests it barely moves: energy saved as a Wurmple prepares Beautifly.
May's Wurmple becomes Silcoon as Jessie's becomes Cascoon, then Beautifly when the other becomes Dustox. Ash and Goh watch several evolve.
Its white silk suggests a silkworm cocoon. Silcoon may combine “silk” and “cocoon.”
