Looks like Knuckles isn't the only tough echidna!
Beau is only 30 days old but he's proving to be quite the rascal at the Taronga Zoo.
The tiny echidna puggle was orphaned at birth and was brought to the zoo after he was found helpless on a trail near Sydney.
It is believed that the babe might have fallen out of his mama's pouch but luckily, he's doing quite fine at the Aussie zoo.
Check out the video (above) to see more of the beautiful Beau!
