Well, it's obviously a bit late for that, but you equip the RAYGUN anyway to be on the safe side. Unfortunately it looks like the OTHER THREE MICE have escaped! So much for THAT particular experiment. You hope that they weren't devoured by the MOUSE ABOMINATION, you had gotten kind of attached to the little fuzzballs. Instead you tell yourself that they simply broke out of the confines of their HOME, and now that they're no longer STUCK they're probably off having nice MOUSE ADVENTURES in their MOUSE KINGDOMS and HAVING FULFILLING MOUSE RELATIONSHIPS and MOUSE SNAPCHATTING each other a bunch of MOUSE MEMES. The thought comforts you.
There were a bunch of COURSES OF ACTION you had been considering in the split seconds before you passed out, but most of them don't seem as relevant now.
What will you do?
