Matter Transformer

A Matter Transformer is a device that allows dimensional travel. A group of aliens purchased a spooky house fitted with a Matter Transformer from 'Honest Lew's Budget Dimensional Travel' and used it to travel between dimensions. However, the Matter Transformer was faulty, and they ended up stuck between dimensions, with the house appearing on Verdant Hill in the Emerald Hill Zone on Mobius. The aliens themselves appeared resembling ghosts. Sonic and Tails investigated, and Tails managed to fix the Matter Transformer by hitting a pipe with a wrench, allowing the aliens to rematerialise and continue their journey.
