From D&D Wiki
Tiny beast, unaligned
Bite. Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 1 piercing damage.
The ember rabbit is the smallest terrestrial creature living in the Flaming Tundra, but it is nonetheless important. It is prey for most larger creatures, such as the firefox. Ember rabbits are white as snow, with reddish-orange eyes. Their large ears are orange in the interior. The rabbits feed on gas grass. As with all creatures in the Flaming Tundra, the ember rabbit has a gas sac in its body that provides warmth, and when threatened, the rabbit can release bursts of flames from its mouth, fueled by this gas.
