Picked up dead cat on the first floor and hoped for the best. It feels pretty awesome to reverse your terrible run by transforming into Guppy
Tell me about it. Just got Golden God after a run in which I accidentally ran into a dead cat that spawned from a gold chest. I thought it was all over but ended up picking up Guppy's Head and Tail on the next floor and had no trouble getting to the end. As a side note, The Nail + Guppy kills everything ridiculously fast. All bosses, even end game ones, went down immediately.
