Blinkwere

Keen Hearing and Smell.  The Blinkwere has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Shapechanger.  The blinkwere can use its action to polymorph into a dog-humanoid hybrid or into a human or elf, or back into its true form, which is a blinkdog. Its statistics, other than its AC, are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Multiattack (Hybrid form only).  The Blinkwere makes three attacks: one with its bite and two with its claws. If it is available it can use its teleport feature instead of a bite attack.

Bite (Dog or Hybrid form only). Melee Weapon Attack: +6 to hit, reach 5 ft., 1 target. Hit: 14 (2d10 + 3) piercing damage. 

Claw (Hybrid form only). Melee Weapon Attack: +6 to hit, reach 5 ft., 1 target. Hit: 13 (3d6 + 3) slashing damage. 

Dagger (Humanoid form only). Melee Weapon Attack: +7 to hit, reach 5 ft., 1 target. Hit: 6 (1d4 + 4) piercing damage. 

Teleport (Recharge 4-6) (Dog or Hybrid form only).  The Blinkwere magically teleports, along with any equipment it is wearing or carrying, up to 40 feet to an unoccupied space it can see. Before or after teleporting, the blinkwere can make one bite attack.
