Corrupted kitsune

Roughly every 20 minuts and 53 seconds, the Corrupted Kitsune releases a wave of cursed energy at 9 different fruits in your garden.  Each targeted fruit has about a 20.2-20.4% chance to mutate into corrupt chakra, a mutation with a x 15 sell-price multiplier. There’s also a very rare chance that one of the fruits mutates into corrupt foxfire chakra, which gives a much higher multiplier (≈ ×90). As the pet ages, its mutation chance increases slightly, and the cooldown time (time between uses) decreases. That makes it more powerful the longer you keep it.
