Mr. Hopp's Playhouse 3 game walkthrough, Final Chapter 

Find The Six Medallions and put an end to The Entity's reign, once and for all.
Six months after Mr. Hopp took everything away from little Ruby during the events of Mr. Hopp's Playhouse, he has come back for more.
After a close encounter, Ruby ends up stuck in The Underworld, a realm where lost souls roam eternally through the darkness. She happens upon another human girl called Esther and together they must solve puzzles, avoid traps and overcome hellish enemies to find The Six Medalions and put an end to The Entity's reign, once and for all.
Run and hide from the toys-turned-monsters; Mr. Hopp, the hair-raising hare, Mr. Stripes, the terrifying tiger, and Miss Bo, the panic-inducing panda. Fight back against giant bosses that tower over you, help Ruby find her lost parents and unravel Esther's troubling past.
Mr. Hopp's Playhouse 3 is an adventure game with light combat elements and a variety of puzzles to solve in order to progress, featuring a graphic style inspired by the early era of 3D gaming on the PS1 and N64.
