Introducing Kamonohashikamo

Kamonohashikamo is an indecisive platypus that can't even be 100% sure that it IS a platypus or not. It is always unsure of anything it does, and often says "Kamo", which means "maybe". The hair on top of its head frequently tells its mood. When curious, it is in the shape of a question mark and when it thinks of an answer, it stands straight up. However, if Kamonohashikamo is too confused, the hair will curl up and Kamonohashikamo itself will turn white and freeze. Kamonohashikamo also has the ability to eat anything it wants, in one bite. Its favorite is the melon bun, sometimes even wearing it as a hat!

Kamonohashikamo is often accompanied by Harinezumikana, a little blue hedgehog (or maybe an echidna?) who, like Kamonohashikamo, frequently questions itself, though its favorite phrase is "Kana".

Also frequent companions of Kamonohashikamo are Ahirunano, a pair of mischievous twin ducks. They were hatched from an egg that Kamonohashikamo found, and the twin ducks love Kamonohashikamo like their mother. However, they are afraid of Kamonohashidasu.

The opposite of Kamonohashikamo is Kamonohashidasu, a black platypus who is certain of everything. It always responds sharply to Kamonohashikamo, and speaks flatly. Its favorite phrase is "Dasu" or "absolutely". Kamonohashidasu views the world as "black and white" with no in-between.
