After being hit by a car the veterinarian proclaimed Sherbert wasn't going to make it and that Tom should say his last goodbye. Heartbroken Tom couldn't stand to say goodbye just yet. Tom restarted the cat dynamics project, one long since abandoned. The cost to reopen, hire, and repair the old laboratories were costly but Sherbert was worth any amount.
Sherbert was revived and implanted with upgrades, an artificial heart, a brain that constantly repairs itself, and laser vision. Any missing fur was replaced with synthetic octo-camo titanium fur so that Sherbert can more easily blend in with his surroundings.
