The Sand Angler is first seen in the episode "The New Kid Part 1" when Eli uses one to create quicksand around Nacho. This armored slug is an Uncommon earth element slug. In "The Journey Home", it's the first Slug that Munch uses against Eli, implying that it is Munch's favourite Slug or his strongest Slug.
In protoform they have mustard yellow skin and a chestnut brown shell. Upon reaching velocity, it looks like a scorpion and surrounds a person with quicksand. In the episode "The Unbeatable Master", a Sand Angler was shot by Trixie at Twist who was disguised as another slinger. It is also seen in the episode "The Hard Part", used by Boss Ember more than once. In "The Unbeatable Master" a Sand Angler is seen being defeated by a Jellyish's Loogi attack.
