Horrorpotamus

Horrorpotamus (デッカーバチャン Dekkābachan Kyōshū, Giant Hīppo-chan's Assault!) is an event added in version 9.8. Like all Gauntlets, progress made in Horrorpotamus will reset when the event ends, allowing the player to collect the rewards again once the event returns. The boss of this Gauntlet is Super Hyppoh, a variant of Hyppoh with a lot more knockbacks, long-reaching Omni Strikes, and a 100% chance to slow Cat Units.

Overview

About

Horrorpotamus contains a total of 60 No Continues levels, called Cosmic Juggernaut Lvs., spread across 3 different maps: Horrorpotamus! (Cosmic Juggernaut Lv.1~20), Horrorpotamus!! (Cosmic Juggernaut Lv.21~40) and Horrorpotamus!!! (Cosmic Juggernaut Lv.41~60). After beating a Cosmic Juggernaut Lv., the player must wait for 30 minutes before they may proceed to the next one. Rewards for the first completion of an Cosmic Juggernaut Lv. can include Battle Items, Catfruit, Tickets, Catamins, Materials and Leaderships. Every 20 Cosmic Juggernaut Lvs. play out the same, but the strength magnifications and enemy base's HP are increased with each level.
