Stinger

Their spiky bodies and sassy nature make them difficult pets that should only be adopted by experienced and well-researched owners! Perfpals in Sandshadow are more likely to own these pets since they're originally from there. Perfpals can often see wild Stingers traveling in herds. 
Whenever a Perfpal is attempting to tame a Stinger, they not only have to worry about being thrown off, but also their electric tail spikes! There is a rumor across Cuddeluna that feminine Perfpals have an easier time taming Stingers.  The bond between Stingers and the pure heart of a young girl has spawned numerous children's movies. 
Their diet consists of cactus. Because of specialized adaptations in their mouths and digestive systems, they can tolerate and extract nutrients from the prickly plant. They can go for numerous days without any sustenance.

Make as many of these as you'd like, any and all perfpals can have these... Though it isn't easy to tame.
