Junk = (hidden food)

C'mon, eat. They're all stuffs you like.

Eh!? But...

These are our treats, don't tell the other guys, okay?

Muku is back!

What took you so long!?

There are smells of crackers, caramel and Imo-Kenpi coming from him!

Even though you guys are going to do the same thing to the Freshmen in the year after next too.

That's no good!
