Definitely one of my favorite episodes. Especially when the fish makes the farting sound.

This video was awesome and funny at the end its the ghostbuster reference (Who you gonna call....GHOSTBUSTERS)

This one got me, I LOVE IT. The way the fish is animated when it sings, gives me many giggles.

Great job!

Heeey I remember those singing fish! :D Actual audio footage of the real thing? I imagine that might not work so well under water hmm... and hey there was a demon there after all! Fun stuff.

Okay, this was pretty great. Holy shit. It's terribly cute and I was getting vibes from multiple popular series all kinda rolled together. I'd say tinker around with this world a little and see if you can come up with something fully TV-possible. You're really not too far off from it now, imo.
TV is of course limiting so maybe just enlist the help of others once you've got a solid idea and let the show live on Patreon support? I dunno, just throwing ideas around, but I see a lot of promise.
