Here's the official bio:
Name and Species: King Brian the Dandy Lion
Personality: Regal, snooty, deluded.
Take a bow because Dandy Lions are convinced they are descendants of Emperor Meow, the legendary Regal Roarer who once ruled over the Barmy Swami Jungle. But they’re not. They’re just silly little Moshlings who enjoy wearing Twistmas cracker crowns and waving at passers by. All hail!
Habitat: Some Dandy Lions make ends meet by performing at Fopkin Circus but most hang out on cardboard thrones in the Barmy Swami Jungle.
Likes: Shaking paws and tinfoil medals.
Dislikes: Press intrusion and commoners.
