Unikitty: Puppycorn!

Puppycorn: Sis!

(Portal appears, and two figures pop out)

Puppycorn: Sis?

Unikitty: Puppycorn? Who are you two supposed to be?

Felicity: I'm you from another universe.

Miguel: And I'm him from another universe!

Unikitty: So you crossed the boundaries of the multiverse to hang out with us? Great idea!
