They went to Nether Nebula

Kazemon: She said the Nether Nebula is somewhere northeast of Cornelia, right?

Agunimon: Time to Hustle and Rustle a little Mirage Muscles.

Goatmon: Just don't Hustle so much that you get yourself lost, okay? We might just leave you there.

Agunimon: Aha ha ha ha! What's the last time I got--

Lobomon: Don't push it.￼

Agunimon: Fine. It like the Time I switched Dogmon's I Can't believe it's not butter. With Real Butter.

Cutaway:

Dogmon is eating a toast with butter. And he realised it Real

Dogmon: (Shocked) I... I.. I can't... I can't... believe...

He got insane and send to the Asylum

Strabimon: I don't know, Doctor. Looking back, I think it have been real butter.

Doctor Digimon: Your friend just destroy two building. In Nine Wood Hills.
