Lily's from Nintendo's Animal Crossing, an ox's from Activision's Spyro: Reignited Trilogy and this screenshot's taken from Valve's Garry's Mod. It is my comedic crossover version of the fairy tale of the same name.

This ox is up to no good, rampaging around some area and causing a lot of troubles. The frog lady named Lily came up with an idea on how to stop and defeat it, by croaking up her belly huge enough for it to be very tight, bouncy and resilient. When it charges at her, she manage to use it as a weapon and shield combined, knocking it out and sending it flying. Once again, justice has been served, baby!
