They spot Slimer flying around a chandelier, which they quickly demolish with their proton packs.
Egon warns Peter and Ray not to cross the streams of the proton packs; otherwise, they might all be destroyed.

When the concierge doesn't want to pay the $5,000 the boys want for their services, they threaten to release the ghost… and the concierge quickly pays up.
