Ath

My old old DnD character, Ath, the satyr druid. Still have a soft spot in my heart.

Her animal companion was a landshark. It was a shark but it had large flippers that it waddled around on land with. Also I guess it could breathe air.
It was cool so I wasn't ever going to question it.
Also it obliterated stuff in battle. Even though it took like two turns for it to turn around. It was not an AGILE beast.
