Meet Lyle. Lyle is a Bane Tangle, sometimes called a Laminaria, which means he’s more like sentient, moderately aggressive, bipedal kelp than any reptile he may appear to resemble. You call him "Lyle the 'dile" and he will seriously blow a holdfast, and probably wipe the intertidal zone with you. On the weekends he enjoys surfing--as long as dweebs don't snake the waves. And Poseidon help them if they do. (2.5 hours in Art Rage 6 and Photoshop CC 2021)
I'm working on a batch of illustrations for Seaborn subclasses and a human variant for 5e.
