Lariat Slugs are light green, water element Slugs with a dark green face, and a foam green stomach. At 100 mph, they shoot out sticky goo that sticks and a tongue that acts as a grappling hook.
- Protoform Abilities - Slug-size climbing rope or grappling hook.
- Wrappler - Spits a loogi of slimy rope, then uses its momentum to swing around an opponent, tying him up.
- Trip Trap - Spits a string at a low level that trips an opponent.
- Elasticrab - Spits a string that attaches to a Slug blaster, then uses its legs to grapple.
- Stringler - Clings to a rock wall and spits a slimy rope for climbing.
- Stinklash - Sticky tongue lashes around foe and emits stinking disgusting saliva.
Lariat slugs aren't usually effective in a fight, but they can be used as a quick escape, as their tongue is sometimes used as a grappling hook. It can also slow moving objects down from behind, as was the case in The New Kid Part 2, when Pronto tried to slow down the train. Their Stringler move makes them very useful in situations with climbing. In the Eastern Caverns, Eli and Junjie used one as a bungee rope at one point.
It could also be a great slug for rock climbers, daredevils, and stunt slingers.

- At first glance, they can be mistaken for a Jellyish when at 100 mph.
- In Snowdance, when Eli uses Larry to climb to the Slyren nest, he states that the goo-rope that Larry made is "So gross!"
- The definition of the word "lariat" is a rope used as a tether.
- The Lariat's velocimorph bares a strong resemblance to a prototype of the Boon Doc's velocimorph.
- The Lariat is one of the only slugs that can be fired underwater without a Torpedo Shell (Jellyish and AquaBeek are the other two)
- A Megamorph Lariat is seen in The Return of the Eastern Champion and the promotial art of Into the Shadows.
