after entering a cave, they spot an underground river. While Mighty takes a drink, molly picks up something shiny.

"What's this?"

"What's whyaah. spit that out right n- oh no" Molly evolves with a big flash and looks down as she now doubles Mighty's size. "Didn't I say don't touch anything!?"

"aw yeah!" she pounces on him "ow there's even more of me to love"

"Just Great"

what I originally wanted for them until I looked at the actual sizes of each in the dex. I thought it'd be fun to have a couple where the lady doubles the guy's size. I like size difference, but don't think its done that way a lot. Arcanine and Mightyenna.
