This milkshake might not bring all the boys to the yard. Hamburger joint Wayback Burgers is mixing things up by adding some protein to its milkshakes in the form of Slim Jims and crickets for the adventurous eater.

According to CNBC, the new shakes will hit the menu July 1. The Oreo Mud Pie shake will be made with Peruvian-chocolate flavored cricket powder -- for protein -- along with a jerky-flavored shake. The jerky shake will be flavored with barbeque, maple syrup and hickory spice and will be garnished with a Slim Jim or two.

President of Wayback Burgers, John Eucalitto, said that the cricket shake originally started out as an April Fool’s Joke, but was so popular the chain decided to bring it back.

The move comes as competition in the fast food and fast casual chains heats up. McDonald’s, by far the U.S.’s largest burger joint, recently beefed up its Quarter Pounders and brought back Lobster Rolls in its New England restaurants. Sales at McDonald’s have been falling and earlier this month it was announced that the chain will shrink for what might be the first time in its history.

Other restaurant chains have changed up their menus as well. Pizza Hut recently debuted its Hot Dog Bites pizza, which includes mini hot dogs in its crust. Meanwhile, Wendy's has been a bit more traditional turning to "Baconator Fries," a variation of their usual French fries topped with cheese, cheese sauce and bacon. Also turning their attention to shakes, Red Robin added a red wine milkshake to its menu late last year.

As for Wayback Burgers' shakes, crickets are part of a trend toward edible insects that are high in protein, fat and essential amino acids. Crickets and other insects are more environmentally friendly since they can be raised on less land and emit fewer greenhouse gases than traditional livestock.

Wayback Burgers' Oreo Mud Pie Cricket shake will be 24 grams of protein, according to the company's site -- in case you were wondering.
