Baby Mimic

The baby mimic holds as much as a regular
backpack.
Toothless maw - when a creature other than
its owner opens the bag without patting it
first, the baby mimic bites the creature. For
1D6 rounds the mimic stays attached to the
creature and causes disadvantage.
Adhesive- the baby mimic can adhere to any
surface on a command word (and released with
the same word.)
