Without the context, the oil-spewing balloon things and the eyeball-filled background just weirds me out completely. *shivers*
Smollusk looks awfully cute and, more importantly, as happy as can be, so the unsettling background seems like a small price to pay to keep Lil'Squirt cheerful. What are those things in the background? They remind me of the Hell Trees of Mario Galaxy. Are they suppose to be evil goop/slime clones, like in Smash Ultimate or pretty much any other fighting game that needs a simple excuse to explain why friends battle one another?
