Kartopia (Expert) is the first stage of the Cat Kart Awakens! stages.
At the start of the battle, 3 Metal Doges will be sent out, with a Metal Hippoe following up along with them. After 30-45~ seconds, an Angelic Gory will come out to support the Metal Hippoe and divert any single-target critical attackers. After the base is hit, Cat Kart P (Enemy) will come out as the boss, supported by three Gabriels, Angelic Gories, and a Metal One Horn, which will come out at a steady rate.
