For the purpose of evicting the unwelcome visitors who've so rudely appeared in our dimension, I've created the S.H.R.E.D.D.E.R. , or, the Sonic Harpoon Revamped with Ectoplasmic Discombobulation Designed for Expunging Revenants. I've designed it to graft neatly onto our very own Blook's arm, since he possesses several unique properties that uniquely suit the weapon. I've even rigged up the device to use FLUX to power it, and with some testing it seems Blook here contains just enough to generate semi-infinite water, AND power the S.H.R.E.D.D.E.R. ! The weapon in question pulls ectoplasm into it and then disperses it using FLUX! Doing so defeats the ghost only temporarily though, since they eventually can reconstitute. If Blook can get to the top of the Apartmall with this, I think the ghosts can be... "convinced" to leave.
