hey i'm back with another suggestion for an ending, what if there was an ending where both Trisha and Jasmine get too sucked into eating that both of them are tied, both too fat to do anything, like the bad ending where Jasmine leaves you useless, but it's both of them too fat to do anything, like a "what did we do?" ending or something.
I originally learned how to program in Ren'Py by 'finishing' a partial game, adding a bunch of content for the quasi-romance branch and a few different endings. If you're really into your idea, I left the code for Unstable Frienemies in plaintext so that it could be played with and tinkered for homebrews (or some light cheating) as the player / end-user desires.
You can even make modifications with baseline text editors - "notepad" suffices - you don't need the (free) Ren'Py utility to modify an existing game like this one. Maybe you would like to try your hand at making a branch of the game you'd like to see?
