They came together to help Ice beat Terraria again, and now they're stuck with each other!
Jazar was the big bull that the other two hid behind, while Hewlett threw things at the monsters and Ice sicced his pets on them. The bosses liked to excluusively bully Ice though for some reason. Hewlett was too slow to get resources, so he ended up getting Jazar's hand-me-downs, awwww~~
