ABOUT DONNIE THORNBERRY:

Donnie Thornberry is the chaotic jungle boy with a wild mane, animal instincts, and a language all his own (which sounds a lot like screeching gibberish). Raised by orangutans before being adopted by the Thornberry family, Donnie is the unfiltered, untamed, and totally lovable ball of energy who never stops moving—or yelling.

Despite his grunts and growls, Donnie has a heart of gold and a spirit that’s pure freedom. He’s the comic relief, the wild card, and the embodiment of childhood unleashed.

How To Dress Like Donnie Thornberry

1. Leopard Print Shorts – Start with some loud, jungle-ready leopard print shorts. Bonus points if they look a little too short and very feral.

2. Barefoot Costume Feet – Since Donnie never wears shoes (of course he doesn’t), slip on a pair of barefoot feet shoe covers for a safe and fun way to go “barefoot” all night.

3. Fake Tongue Prop – Donnie’s iconic deranged expression isn’t complete without a flopping fake tongue. The sillier, the better.

4. Red Temporary Hair Spray – Spray your hair (or a wig) with bright red color to mimic Donnie’s messy mop. The goal: look like you just rolled through a bush—and liked it.

5. Fake Teeth – Add a big goofy pair of over-the-top fake teeth to sell that wild, wide-mouthed cartoon chaos.
