How to Cheese (The slime gets old at the moment when it switches from 11:59 PM to 0:00 AM every day (the "ほつう (Steps)" for each day is also reset at this timing).
In other words, the slime will never grow old and will not reach the end of its life if you change the clock to after the reset time happens. Specifically, if you change the clock at 11pm to 1 am, then the vpet doesn’t count a day as passing by, so you can build steps without having to worry about your slime dying) 幻のエンディングキャラ Phantom Slime (fan name dub) - 3rd Generation death screen only, not obtainable
