The sidesnagger is a Spartan eater found by Chris Cain in May 2015 with functionality similar to the tub-with-tail eater, as shown to the right. It has one lane less diagonal clearance on the high-clearance side than other TWIT eater variants, due to the presence of the boat. The sidesnagger can be used to stabilize the p130 shuttle as discovered by Tanner Jacobi on November 18, 2017, whereas other TWIT eater variants would be destroyed by it.
