Shrimp Jump is the third exclusive ability for the S.H.R.IMP's mech in Plants vs. Zombies: Garden Warfare 2. When used, the S.H.R.IMP's Mech will jump up and forward in the air, before coming back down with a damaging ground pound, dealing up to 50 damage.
This is much more useful than the S.H.R.IMP mech's other ability, Water Cyclone. This is very similar to the Rocket Leap for the Foot Soldier as you can use 2 of them and this is meant to close distances to your enemy. Like the Dragon Swoop, you can use this to finish off enemies and unroot Pea/Retro Gatlings and Sun/Solar Flare Beams.
