The pandas want to collect the same amount of points the following sentence is worth:
"I am the fabulous [Insert your steem-name here]."

This is what it's for. The pandas want to produce points to make their sentence xD

Every working panda drinks 1 L of water and then produces 3 points in the next 1 hour.

So they drink 1 liter of water, then produce 3 points, then have to drink again to produce more.
