One of YouTube's early viral hits, Charlie the Unicorn is back with its first installment in three years.

Charlie the Unicorn 4 is a mini-adventure in which Charlie visits the moon, defeats the mysterious Millipede (but only after singing a psychedelic tune) and narrowly escapes death with the help of his friend, the Starfish. If you're a fan of past Charlie videos, this will not disappoint.

The first Charlie video was released in 2005, the same year YouTube launched, and became one of the network's big successes with more than 60 million views. Sequels to the short film hit YouTube in 2008 and 2009.

What do you think? Does Charlie still have it? Let us know in the comments.
