Basically the "new" ad item Blobby lets you do some cool clips and stuff that would definitely save time in some places, and can work as a (slower) replacement for the sword. Make sure you get the item and save a costume with it, since it says that it's limited time only.

what ad?

i believe if you go on the map and go to the second page, there will be an ad for hotel transylvania 3, watch the video and get blobby. it's actually kinda insane what you can do, i've doing some testing it's wild. place enough blobbies in one room and sometimes you will clip through floors.

Well, it was fun while it lasted, but the ad is gone and the costume with it still works, but the item disappears when you try to use it. rip
