Don't be a Muppet buying this game.
AllMuppet characters travel and end up trapped in Castle Von Honeydew on the scariest night of the year Halloween, all the charcters get turned into Monsters except for Kermit's Nephew Robin who has to save his Muppet friends and make everything back to normal.
Gameplay was alot like Spyro series becuase of the controls felt like a Spyro game you can swim and climb. Alot of easy platforming elements and most puzzles and bosses are very strieght foward and you can get the game less then 5 hours in one go.
Graphics look like a double of Crash and Spyro but the graphics on the Muppets were poor and badly looking for a game on PS1 comparing to popluar titles such as Tomb Raider or Final Fantrasy 8 they had great graphics. Muppet Monster Adventure did had one good about this game was voicing from Frank Oz or Jim Henson.
If your a muppet fan or a PS1 collection I wouldn't bother getting this game at any price it's selling at.
