Takotaku (and their western counterparts, the Otakupus) are most easily
recognized by their soft, pullover-shaped shells, and love for completely
useless information. While an eastern Takotaku could tell you the
birthdays and bloodtypes of each of the characters in the epic "Record of
Lodoss War", a western Otakupus thrives on the exact mechanical specifics
of every ship ever to make the Kessell Run, and could recite the entirety
of "The Hitchiker's Guide to the Galaxy" in Klingon.
A Punkemon trainer can tell when Takotaku/Otakupus are in the area by
their loud call of "d00d!", which is not a mating call as much as an
attention-getter to begin the exchange of information. Often returning the
call will cause a curious Takotaku/Otakupus to waddle over to you for easy
capture.
