Episode 1: Green Hill's Lost Valley

When the HUGtto! Pretty Cure was having a picnic at the park, they are sent to Mobius by the Phantom Ruby, with Dr. Eggman wanting to steal the power of the Pretty Cures for his conquering conquest with the Phantom Ruby!

So now with the Pretty Cures scattered all across Mobius, they must combine their strength and power with the Resistance and Futari wa Pretty Cure, along with Classic Sonic and other Precure teams to stop Eggman's Army from taking over all of Mobius. All the while, Cure Yell is curious about the mysterious and tragic masked Jackal called Infinite.

(This is kind of a mixture between the HUGtto Precure & Futari wa Precure All Stars Memories and the Sonic Forces game, don't know about copyright, so sorry!)
