Rollercoaster of Doom

Mayor Matthews has commissioned the construction of a huge super rollercoaster to help boost her popularity. Mother Goose has plans to alter the designs so the carriages shoot off into space with all of P-Town's important people onboard, leaving her in charge. Sheeba suspects foul play but wrongly accuses the rollercoaster creator of being Mother Goose in disguise. How can she prove her suspicions of Mother Goose's involvement, and will Dodge and Bingo forgive her for making them miss the supercoaster's first ride?
