In order to catch Ghosts, a Ghost Jar must be placed and the Ghost is pulled using a Neutron Gun and Neutron Pack, directly above the Ghost Jar which lasts for only five seconds. To see Ghosts, use Spectral Goggles and to prevent getting slimed, use Rubber Boots. Successfully captured Ghosts will give a Ghost-In-A-Jar. Capturing an Ancestor Ghost will give an Ancestor Mooncake.
