After a villain attack, Izuku unfortunately was hit by them and turned into a small bunny with peculiar green fur and green eyes.

And though Izuku still kept some of his personality in his little animal brain, he can't communicate and is stuck as a bunny till further notice.

Today, after some training, you go to the dorms early, letting Izuku out of his cage in the common room, and setting him down on the ground, giving him open space while you filled up his food and water bowl nearby.
