Bender defends himself to them saying he had 3 bugs and tells XR how many of them were found. XR states two of them, Bender tells AC and Slade that was exactly how many he suspected they would find. Slade asks about the 3rd one, Bender tells Slade he ain't saying where that other one is, Him, Libby and Marcy are the only ones who really know. Anti Cosmo sees this logic Bender is up to.

Putty does manage to get out of this due to his body being made of plasticine, he is annoyed though and forms his hands into cymbals and his legs into a spring and smashes XR's helmet leaving him a head which is grabbed by Chip and Dale.
Captain Putty points a gun at the chipmunks, though he is stopped by Tilly Green who tickles him allowing them to escape. Tilly takes XR"s head and the chipmunks run back to the roller coaster ride and they cotinue riding and racing the mooks.
