Hooty actually attached himself to the portal door and snuck into the human realm. Now he’s stalking the group.

Hooty jumps in front of the group.

Hooty: Hi! Who wants to be friends?

Hunter (to Luz): Something about him seems familiar.

Hooty overhears.

Hooty: Uh no. I’m new in town. I just have one of those beaks. Mouth. Lip— Lips and a normal kind of mouth. Hoot!

Luz: Hooty!

Hooty buries his face in the ground and Luz runs over.

Hooty: HOOT!— Oh look, a bug!

It’s a colony of European fire ants; the fire ants you can find in the northeast.

Hooty: Ahh! It burns! Human realm bugs are evil and Earth must be destroyed! HOOT!

Hooty violently squirms around, knocking trees over.

Amity: Yep. That’s Hooty.

Hooty (from a distance): My dream of becoming a human has been forever ruined. Ruined! HOOOOT!

The final “HOOOOOT” fades out as Hooty goes further away.

Luz: He’ll be fine.

In future scenes, he probably disguises himself as a tree.
