Attack of Opportunity
A creature within the monster's reach uses a manipulate action or a move action, makes a ranged attack, or leaves a square during a move action it's using.
The monster attempts a melee Strike against the triggering creature. If the attack is a critical hit and the trigger was a manipulate action, the monster disrupts that action. This Strike doesn't count toward the monster's multiple attack penalty, and its multiple attack penalty doesn't apply to this Strike.

Melee Jaws +12 (unarmed), Damage 1d8+6 piercing
Melee Tentacle +11 (agile, finesse, unarmed), Damage 1d6+6 slashing
Unbalancing Blow
Any creature a grick critically hits is Off-Guard against its attacks until the end of the grick's next turn.
Vermicular Movement
When a grick takes a Stride action to move half its Speed or less, that movement doesn't trigger reactions.
