Everfree Monsters

Does anyone have any ideas for possible Everfree Forest creatures that could be shown in future episodes?
 
I think we should use more mythical creatures. And I wouldn’t mind some prehistoric ones either.

A hairless a-

Demon Snakes and a flock of Demon Crows.  
Giant Spiders  
Apparitions  
Stolas

Cyber-demons, uniclams and a single zombie chained up decades ago and accidentally set free by Derpy.

At this point just about anything from classic Greek myth would fit perfectly.
 
A gorgon pony would be awesome.

Carnivorous Plants  
mutant toads  
Sabre tooth tigers  
Moss Behemoth

Bronies  

Netch  

Literal Mountain Lions.

Literal Rock Pythons  
Golden eagle
