After the dimensional bleed incident, Holtzmann starting work on converting a zamboni into a mobile Ghost Chipper. Abby Yates cleared Holtzmann to use the zamboni on Doctor Kruger in the Firehouse even though it wasn't close to being ready. Holtzmann couldn't believe she could finally skip safety testing for once and pulled the tarp off it in the lab area. Kruger resisted the Ghost Zamboni's pull and burst through the upper floors, escaping into the city.
