Root Canal moved in with the saw again, but CUAD charged Root Canal, slamming it against the wall, and Root Canal stopped moving. The fight ended before Root Canal could be counted out, but it still lost the fight on a 26-19 decision. CUAD moved on to fight 2925 Jack Rabbit.
CUAD had such severe control problems that he ran right into the wall as the match began. They then started darting around each other and trying very hard to line up shots, and not succeeding very much. Jack Rabbit missed CUAD by inches and ran into a wall again, and this time it was the wall that won. Jack Rabbit threw a chain on the right side of its drive because the magmotors bent the drive shafts from the hit. CUAD then got a few shots on Jack Rabbit, wedging under it and hitting at the same time, and Jack Rabbit got a few more hits on CUAD. The judges scored a 25-20 decsion in the favor of Jack Rabbit, and CUAD was out.
