Emperor hamsters are 3 to 4 feet tall. Your size is small.

Your base walking speed is 25 feet. Your base burrowing speed is 10 feet.

You can see in dim light within 60 feet of you as if it were bright light, and in Darkness as if it were dim light. You can’t discern color in Darkness, only shades of gray.

As an action, you can summon a swarm of hamsters. The swarm(s) will stay around for 1 hour or until slain, and will follow simple commands.Use the Swarm of Rats in the Monster Manual for reference. An additional swarm is added at levels 5, 10, 15, and 20. You can use this trait equal to the number of swarms per day.

You have advantage on Perception checks that rely on smell.

You can use your bonus action to roll your body into a ball. While rolling, you can't take any actions, but your speed doubles and you can move through the space of medium and smaller creatures without treating them as difficult terrain. When you move through a creature's space, the creature must make a Dexterity saving throw with a DC of 8 + your proficiency bonus + your Dex modifier or take 2d4 + your DEX modifier bludgeoning damage and be knocked prone.

You can use your little hamster jaws to bite as a melee weapon attack you are proficient with which deals 1d4 + Strength modifier piercing damage.
