# The Hippo Harem The Hippo Harem is where users manage their HouseHippo NFTs. The males and females will be divided into two sections and each of them will have their NFT ID's displayed. The dApp will inform users whether their males are in cooldown or ready to mate, and which females are pregnant, ready to give birth, or ready to mate. To mate the hippos a user will input the ID of the two hippos they want to mate, and then the female will immediately become pregnant, and the male will enter a cooldown period. The dApp is also where a user will access the HouseHippo marketplace to trade/sell their HouseHippos. A section within the dApp called the Tavern will also be available to purchase shots of maple syrup for the males to reduce their cooldowns. Hippos will not be born automatically after the four day gestation period has passed, Users will need to submit a blockchain transaction, "Give Birth" in order for them to be born. To breed, give birth, drink maple syrup, or buy/sell/trade users will be required to gas in BNB. The chain was chosen to be gas efficient enough that each transaction should be no more than a few cents, and the rewards should far exceed the gas being paid to manage the Hippos. Artwork for the Hippos and the Hippo Harem is currently underway and the dApp will be in testnet in September. This section of the Whitepaper will be updated to include the artwork and screenshots from the dApp at that time. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
