MacGruber went to lie down on your lap, like he usually did - but with the difference in bodies now, he nearly crushed you! You tried to tell him to move, but all that came out was a bunch of woofs and whimpers.
"Are you trying to say I'm fat?" MacGruber asked, somehow understanding you. So on top of looking like Katie, he was starting to act like her too? The concept made you laugh a little bit... well, more like pant a little bit. "You're the one feeding me, don't act like it's my fault!" MacGruber said as he started to sit up like a person - which he was now, sorta - and put his hands on his new stomach, which came as a relief. "Hey, I haven't gained weight!" he noted. You tried explaining to MacGruber through barks... somehow that you were just small and he was just big.
