Grossmos... Wish they had existed when MOTUC was a thing:

 You know Miniverse and MiniBrands... they have various spinoffs and stuff like appliances, shops... well the Makers of Miniverse have Grossmos... Dinosaurs plus Slime.

Here's a video ad for it.

The Dino Head and Opening Jaw drew me in... but most importantly the wrapper is plastic slime. You see where I'm Going with this?

Had this been made in the MOTUC Era, a Custom Slime pit would've been doable...

I got 2 from a Mom and Pop pharmacy ready to write a rant about the potential for these...

Somebody else already saw the potential of the plastic wrapper for the Grossmos. Now I need a Slime Fright Pit. Now you know and knowing is half the battle.
