Ahh, that special time of year where we think about sharks more than we normally do. July 22 marks the start of "Shark Week," which is a block of TV programming themed around sharks. Presumably to celebrate the occasion, Fortnite has added some new shark-themed items.

These include a "Chomp Sr." outfit (2,000 V-Bucks) and the "Chomp Jr. pickaxe (1,500 V-Bucks). There is also a new emote called "On The Hook," (500 V-Bucks) which shows your character reeling in a fish (or a shark, I guess) and then showing it off with a smile on your face. All of the items are cosmetic in nature only, just like everything else in the game.
