Trapinch (5e Creature)
From D&D Wiki
Small dragon, any alignment
Arena Trap. The ground in a 10-foot radius around the trapinch is difficult terrain. Each creature besides the trapinch that starts its turn in that area must succeed on a DC 12 Strength saving throw or have its speed reduced to 0 until the start of its next turn.
Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) bludgeoning damage. If the target is a Medium or smaller creature, it is grappled (escape DC 12). Until this grapple ends, the trapinch can't bite another target.
