Unexpectedly Good!
This was a great cartoon! I loved the contrasting themes within. Everything was all morbid and creepy in appearance, but very lighthearted in the plot and events. Throughout the whole cartoon I was expecting one of the creatures to do some nasty jump-at-the-screen-and-make-you-jump sort of maneuver (especially that big thing at the fork in the hallway at the end) but never did. It kept in tune with the fun feel of the plot.
Overall it felt sort of on the same lines as an old Looney Tunes short with Wile E. Coyote and the Roadrunner, if you took the characters and replaced them with oh-god-what-the-hell-are-those things.
This was really awesome, keep up the good work!
