Tadpole

The tadpole (オタマシャクシ, Otamashakushi) is a fish (technically an amphibian) introduced in. It lives in ponds, sharing its spot with crawfish, killifish, and frogs. As with all fish found in the pond, tadpoles are sold for little bells. It is unknown what species of frog the tadpoles are, but they are most likely the same species the frogs are.
