They (or at least, a colony of them) were taken to Faerieland by the Air Faerie Casandia, but their great appetites caused a problem. Before they could be removed, they were rounded up but the cloud could not support their weight, and they plunged into the waters far below. They washed up on Mystery Island and used makeshift see-saws to take Doughnutfruit from the trees. Their over eating caused the islanders to contact Fyora for help, who had most of the Hasees rehomed in Petpet shops.
As of June 2012, the Hasee can be painted 17 different colours:
- The Hasee was selected for Week 82 of the Petpet Protection League.
- Hasees are featured in fourteen items (excluding the Petpets themselves).
- A Hasee is featured jumping across the 'Success Pending' window when a user chooses to 'Send' their score in Neopets' Flash games.
- A Hasee can be combined with another petpet in the Cooking Pot. GX-4 Haseebot is a mixture of GX-4 Oscillabot and Hasee. Haseepuss is a mixture of Angelpuss and Hasee.
