DB Multiverse

The next day...

I brought back 10 Gloose from 10 other universes!

...and none of them invented this stupid detector. That proves he made it by pure chance!

Mad Duck from ​my​ universe didn’t find his travel invention either!

Still, this is proof I travelled to other universes.

Or you made a cloning machine.

Thank you Prof. Mad Duck. Dr. Gloose, what do you have?
