The Snow-a-constrictors (or Strangling Snow Snakes) first appear in "Earth & Water." Gunter creates them using Ice King's crown, which Ice King gave Gunter to rebuild the Ice Kingdom. It is unknown why Gunter creates them, though it is evident that Gunter does so on purpose since they do not strangle him/her. Princess Bubblegum helps Finn, Jake, and Ice King defeat them, presumably by using her Ball Blam Burglerber (though this is not shown).
The snakes are long and made of packed snow. They each have two eyes and a wide mouth with a long forked tongue.
- Their name is a portmanteau of "snow" and "boa constrictor."
