While walking around Jabberwock Island, Hajime has access to a virtual pet that grows based on the number of steps that he takes. The pet has four stages of growth: an egg (which takes 100 steps to hatch), Chibimi (which takes 1000 steps to evolve), a cocoon (which takes 100 steps to evolve), and its final evolution. The way in which the pet develops depends on how Hajime interacts with it. He can interact with it by giving it presents (the cheapest of which is Mineral Water, purchasable at the vending machine in Rocketpunch Market for one Monocoin) and by cleaning up after it, or by neglecting to do either of those things. Giving your pet any present will raise its hope, and failing to clean up after it will raise its despair. If its despair gets too high, your pet will die and you will forfeit your potential rewards. Below is a list of pets and tips on how to ensure that they fully evolve so that Hajime can receive their rewards after they depart.
