Katy Perry's halftime performance at the Super Bowl has been remembered for one thing: Left Shark. 

People loved his or her laissez faire attitude to choreographed dance, and so they were forever immortalised in internet meme history. Obviously, that has lead to a huge demand for Left Shark onesies...? Really? 

Well, that's what Katy Perry is banking on anyway, as she finally has a range of merch honouring the privileged position that Left Shark has in music history. We're not sure how many are going to sell though, as they will set you back $129.99 (€118).

If you want a slightly more reasonably priced piece of Left Shark gear, then there's also a t-shirt for $25, but the onesie is still the truth. Besides, it makes for a better costume than this.
