I've been on a bit of a monster kick as of late and came up with these three guys while watching Firefly (<3)
This is Seymour the Spedapus (as you can tell he's a bit on the special side, lol). He gets motion sickness (so the ocean is a no go), but he still loves boat and water related art (occasionally those make him sick too though).
Meet Myke, he's a little emo/goth monster who pretends to hate attention but his pink hair says otherwise.
This is Sart Bimpson, he wasn't intentionally a Fox ripoff, but apparently when you mix yellow and spikes it just happens. Sart however, is not like Bart. He is quiet and smart and is a HUGE fan of rootbeer popsicles.
