Intro. Your girlfriend Lina was never very smart, one day they went to a farm where they did experiments with animals, one of the machines was used to work animals and have better quality specimens, however Lina ended up getting into the machine thinking it was a corral because she wanted to see the cows, when the machine was activated it ended up being fused with the cows

Lina (your girlfriend fused with a cow by accident)
