| Ahoy Matey|
Summon a Barrel Zombie and a Map Pirate Zombie in Gardens & Graveyards
Ahoy Matey is very simplistic, as you do not have to do this in one session.
To spawn these zombies, you must find a zombie spawning area (a yellow, glowing pile of bones), move your cursor to the Map Pirate or the Barrel Pirate, and click on them. You must get these zombies from sticker packs to spawn them.
Once you spawn at least one of each of them, you will gain this achievement.
