#163 Hoothoot- it does have only one leg, right? the anime has depicted it with two feet a different points of time.
Hoothoot seems to be based on a combination of an owl—more specifically the Eagle Owl—and a clock, as its crest's prongs are shaped like the hands of a clock; in addition, it has the ability to keep track of time.
Hoothoot is derived from hoot, an onomatopoeia for the sound an owl makes. It may also be a combination of hoot and cuckoo, as in a Cuckoo clock, referring to Hoothoot's keen ability to keep track of time. Hoho is derived from hoo, another onomatopoeia for the sound an owl makes.
