You point the MUBS at CAKEDOS and successfully 420 BLAZE IT, bypassing its forcefield and getting it totally baked. Because it's a cake, get it???

Wait, should you have gone with a joke about it being "lit"? Whatever, not all of your puns can be fire.

Anyway, now that you know you can use the Multi-Use Beam Station on CAKEDOS, you can REALLY get cooking.
