When Spin shoots out of the cannon, he comes apart completely on impact with the rock-face. In the next shot, however, his head and left arm are re-attached.
SPOILER. When Junkman's junk-bots confront Slick and Spin in the castle, they are standing single-file. In the next shot, between the Crash Dummies and the junk-bots, weapons are seen pointing at the Dummies from the top and bottom of the screen, indicating junk-bots standing behind each other.
SPOILER. Chip and Dent enter the castle along with the rest of the Crash Dummies, but they seem to disappear after Junkman crashes his helicopter.
