A rare zedonk, born to a zebra mother and a donkey father, has been identified amid the wildlife of the Chyulu National Park in southern Kenya, an animal rescue group said.

The Sheldrick Wildlife Trust said its fence-maintenance squad noticed the zebra mother had a small foal by her side with a bizarrely brown body. Initially, the wildlife team chalked up the animal’s hue to a bath in some mud.

On further examination, though, they realized they had discovered a zedonk — or debra, or zonkey if you prefer.

“Working with wildlife, one learns to expect the unexpected,” the rescue group said in a news release on Wednesday. “Even the most seemingly straightforward story can eventually reveal its true stripes and end up surprising us all.”

The zedonk is thriving, according to the rescue group, but its mule status will prevent it from reproducing in adulthood.

The an animal is clearly of a different stripe.
