This is a genet, a little fella from Africa related to the civet and mongoose.
This is an African Cape buffalo.
This is a genet riding on top of a buffalo in Africa.
This is the same genet riding on top of another buffalo.
This crafty little guy was caught hitchhiking by a camera trap in Hluhluwe-iMfolozi Park, South Africa. It isn't yet known if this is somehow symbiotic, mutually beneficial behavior, or if this is a singular abnormality, the one genet who can ride a buffalo like a boss. But the first buffalo did shake the genet off.
There's more at the park's website where they published the camera trap photos.
