Three Hyenas (and a hippo)

So, I've been watching Lion Guard recently. And like any Lion King fan I was in the mood to draw the three different species of Hyena (Striped, Spotted and Brown) I also threw in a hippo, because everyone knows that hippos are the true villains working behind the scenes. Hippos are gnarly. Why aren't there more evil/killer hippos!
Anyway, we got a vain Striped Hyena (they have the most 'worth it' hair of any animal) who'd be best pals with Thurston, despite being a, you know, hyena. I imagine they'd get along splendidly.
Then a spotted hyena that has no sense of humour. So serious...so grumpy...needs to chill out and learn there is always time for a laugh or two.
Cujo but a hippo...Fujo if you will (I'm sure Fujo means 'mad' or something in an African language)
An ever-hungry brown hyena that came to mind whilst watching Dracula films.
