Callopode

allThe Callopode is a strange creature from Lumberjack Folklore. It has the “scientific name” Musicacorpus tryoni. They make music at the start of spring. They breathe in through a hollow knot on top of their heads and breathe out through their trumpet-like noses. They have been known to cover some of the holes from the five rows on its chest to change the sound.
