Interdimensional Traveler

You hand Doki your Interdimensional Traveler, and he analyzes it.

"To go to that dimension, you want to press "4-2-9" on this control. Be careful, though...it's a fun place, but it can be a crazy place. Also, I have a clone brother there. If you meet him, tell him I said hello."

"Sure, Doki, no problem."

He gives you back the Interdimensional Traveler, and you start to punch the code in...
