Hungry World was a part of the Hungry Wolves project.

Hungry Wolves as a collection is now part of White Sands, an interactive world built on the HYTOPIA platform. You can read more via this announcement: https://hungry-wolves.gitbook.io/whitepaper/

Each Hungry Wolves NFT now acts as an item bundle inside of White Sands, yielding interactive pets, vehicles and clubhouse access. The items you receive in-game depend on your wolf's tier trait.

This is the capstone utility of the Hungry Wolves collection and after a 2.5 year run, all other games and features have been sunset. Sheep from Hungry World were utilized during this period as a way to earn Dominance and upgrade your wolf. They now remain on the blockchain as collectables but have no further function.
