Yoohoo Monster: Monsters Unchained

Many say that Monsters don't exist and that they only exist in legends and stories, but what if this wasn't the case when the nefarious Big Boss activates a device that summons these dangerous and deadly beings? Not only that, but several humans turned animals were accidently transported to this new world shortly after the Monsters were summoned. Amidst this, Yoohoo and his friends get pulled into the madness of a chaotic new world.

Joined by the four Busters along with a nature lover and Monster expert who may have a big secret of her own, the group battles their way through a world now filled with Monsters and Undead while trying to restore their island to how it was before the crisis while also trying to find a way on sending their new friends back home to their world. Can they do so in time while trying to keep everything under control?

Inspired by @FubukiVolt's Yoohoo: Undead Unleashed and a lot of the ideas and concepts she came up along with a few twists from me.
