Bloober (also Blooper) is a jerky squid that’s appeared in most Mario games. They’ll squiddle around and seek directly after Mario or Luigi in an attempt to stop the hero’s underwater progress. And in SMB3, they were occasionally trailed by the Baby Bloobers, which were like the same thing but smaller.
Also, because I like its name, I drew Jelectro! See, it’s a JELlyfish, and it’s ELECTRIC, so, JELECTRO!
Despite the similarities in their names, Jelectro is not the sassy jerk from Spider-Man.
