FROG

FROG is a cryptocurrency that has gained attention for its unique approach to wildlife conservation. It's a Proof-Of-Work/Proof-Of-Stake (PoW/PoS) hybrid blockchain with Master-nodes, designed to raise awareness for declining frog populations globally and support non-profit frog foundations. The FROG token is also used within the Old School RuneScape game as a reward for the “Kiss the Frog” random event, exchangeable for royal frog costumes and other items . Additionally, there's a project called Travel Frog with its native token FROG, used for in-game transactions, staking, governance, and exclusive access to features .
