Katy Perry is cashing in on the viral success of her Super Bowl shark dancer by releasing a onesie based on the character.

The singer performed the half-time slot at the American football event on February 1 in Arizona.

One section of the show saw the US star perform in front of two people dressed as dancing blue sharks.

However, the character on the left of the screen appeared to forget the moves and make it up, becoming a viral internet hit in the process.

Perry has now revealed on Twitter that she is selling a Left Shark onesie.

She posted online: "YOU CAN NOW BE A PROPER #LEFTSHARK WITH THIS OFFICIAL, GLORIOUS #LEFTSHARK ONESIE."

The onesie is priced at $129.99 (£84.53), whilst a Left Shark t-shirt can be bought for $25 ($16.26).
