The problem you faced last time dealing with the grinning wraith was he was nearly impervious to any physical attacks. However, you had to hand it to the ghast busters, they had a solution...

Dr sheens weapon being far from offensive was more utilitarian. He sprayed the wraith, making it not only somehow slip up, but it also became weaken to physical attacks. Between the 4 of you, you were able to dispel the creature again. 

While considering their next moves, another undead appeared. You readied your weapon to swing, but were stopped by Dr sheen. Incredibly, he explained this creature was more akin to a slime than a ghost and the team had become rather fond of it, making it part of the team.

... this day is filled with surprises, it seems.
