Mob New enemy types (not just walking and flying)

Probably planned anyway, but I'm sick of just seeing terrestrial and airborne enemies. I want giant worms! Fish that fight back! Eels! Swarms of tiny enemies! More size variance! Hungry plants! Things that lurk in pits! Sentient liquids with random organs! Things that climb!
...I think you get the picture...

 

you're right we need some more ememy types in dis game

 

The random powers are great, but they'd be so much better on, say, Terraria-esque worms, etc.
