This absolutely brilliant marble is a collab between Rob and Stephen. I'm reluctantly releasing this gem from my collection, but oooh does it hurt because this one is SOOOO fun! It features Steve's mushroom people set in front of Rob's birch trees. The whole scene totally reminds me of Dr Seuss, thanks to the trees, and if mushroom families exist in the world of Dr Seuss, then this is them! It's just a wildly cool marble all around, 2-sided, and the mushies are chock full of UV and light up brightly under the black light. I know someone is gonnna love this one like I have!
