Tom succumbed to corruption, leaving him and Jerry powerless against the Darkness. This cat-and-mouse pair fell victim to its malevolence, which meant Boyfriend was once again too late to prevent the Darkness from tainting various universes and characters. Soon, more realms succumbed to its grasp. Boyfriend found himself teleported into Tom and Jerry's home, but in a diminutive form, only 25% of Tom's height. He had to engage in a musical battle against the corrupted Tom, who had transformed into a grotesque version of himself due to the corruption. The two faced off in a musical duel featuring the track 'Mouse Chase.' Midway through the performance, Corrupted Tom began to utter nonsensical phrases in a garbled voice, continuing to sing alongside Boyfriend, who desperately tried to defend himself musically. However, Tom's intense singing drained Boyfriend's health significantly, leading to Corrupted Tom's victory. Now, Boyfriend must flee before he too falls victim to Tom's corruption and becomes part of the Pibby Corruption.
