Dave, it was once like this

Holly used an alternate universe machine to open a portal to ABU, and is a character. Callahan is a monster in the universe Holly comes from and tells her to do experiments. She travels to Rin's universe and kidnaps her, performs experiments on her in secret, and makes Rin into a monster. Holly then, unleashes it upon the birds, with them knowing she made it, and whatever happens next.

Now due to Combo redesigning the entirety, it's now like this

Terrolly is an incarnation of Evil Callahan. He came from an alternate dimension who tricked Holly into making Terrollies, and Holly wasn't done with them when the events of the Spooky zone take place. (Also, Evil Callahan is not playable, he is seen once. You are getting Evil Callahan confused with Callahan.)

And every event in ABU is non canon to the ABUniverse (ABU universe), Except for the Knitter Event.
