A hedgehog. I know everyone else is going for mythical ones but please try and fail to convince me that hedgehogs aren't whimsical. They're tiny adorable waddling grumpy balls of spikes what could be more whimsical than that
Hobbits never have to wear shoes so that right there is enough for me. I see from comments now that you meant an animal and not a fantasy creature, but I'm sticking with it. A pre-Shire hobbit though so I'm not burdened by class relations.
In Japanese folklore, kitsune (狐, きつね) are foxes that possess paranormal abilities that increase as they get older and wiser. According to folklore, the kitsune-foxes (or perhaps the "fox spirits") can bewitch people, just like the tanuki they have the ability to shapeshift into human or other forms, and to trick or fool human beings. While some folktales speak of kitsune employing this ability to trick others—as foxes in folklore often do—other stories portray them as faithful guardians, friends, and lovers.
Gwragedd Annwn, just chilling in a lake, guiding travellers to the lower world, fucking up farmers as punishment for mistreatment of animals. If my exploits spread far enough amongst the fearful townsfolk they may even build a statue of me.
