Scorpion
The Scorpion is a 
Tier 5 Pet, available in the 
Turtle Pack. When summoned, it will gain 
Peanut perk, which instantly knocks out any enemy that's hurt by Scorpion. Scorpion's ability does not change on level up.
Strategy
Scorpion is an extremely cheap investment that can instantly take out big enemies with high stats. It's generally put frontmost since this is where high scaled enemies are often positioned. Due to being designed as an anti-scaler, it does not work well against summon teams.
Despite being an 1/1, it poses a very serious threat and is something most teams have to prepare counterplays for. This often means putting 
Melon on the frontmost pet to block the Scorpion, putting a weak pet in front as a meatshield, or bringing along a 
Dolphin to snipe it.
However, there are also counters to these counterplays. When paired with 
Whale and/or 
Mushroom, it can break the Melon/knock out the meatshield/tank the snipe, then revive with Peanut to knock out the big enemy. A Scorpion with 21 attack or higher can also hurt the enemy through Melon and knock them out in a single hit.
Overall it's a very simple yet dangerous pet that can fit on almost any team. It can help scaling teams to gain advantage over other scalers, or help summon teams to get rid of the troublesome tanks in the front.
