Bite. _Melee Weapon Attack:_ +4 to hit, reach 5 ft., one target. _Hit:_ 4 (1d4+2) piercing damage.

Sting. _Melee Weapon Attack:_ +4 to hit, reach 5 ft., one creature. _Hit:_ 4 (1d4+2) piercing damage plus 2 (1d4) poison damage, and the target must succeed on a DC 11 CON save or be poisoned for 1 hour.

Puff of Smoke (1/Day). The pseudodragon exhales a cloud of smoke in a 10-foot-radius sphere centered on itself. The sphere spreads around corners, and its area is heavily obscured. It lasts for 1 minute or until a wind of moderate or greater speed (at least 10 miles per hour) disperses it.
