3/day: Enlarge and Reduce. As an action, the spacious otter is able to cast the Englarge and Reduce spell thrice a day. It is however only able to grow as big as a Large creature, and shrink as small as a Tiny creature. The standard size for the otter is Small.

Enlarge. The otter's size doubles in all dimensions, and its weight is multiplied by eight. This growth increases its size by one category - from Medium to Large, for example. If there isn't enough room for the target to double its size, the creature or object attains the maximum possible size in the space available. Until the spell ends, the target also has advantage on Strength and Strength Saving Throws.

The otter can enlarge itself to a maximum of a Large size.

Reduce. The target's size is halved in all dimensions, and its weight is reduced to one-eighth of normal. This reduction decreases its size by one category - from Medium to Small, for example. Until the spell ends, the target also has disadvantage on Strength and Strength Saving Throws. The otter can reduce itself to a maximum of a Tiny size.

Actions

Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: (1d6 + 1) piercing damage.

This creature originates from the Feywild, but since travelers have brought them to the normal world, they've become more common through the years. The otters can become about 200 years old and are extremely loyal to their owner(s). Their lifespan makes it so they are valued companions of Eladrin, both as pets as well as mighty steeds in battle.
