This is played as described on the box. With this version, you are trying to collect as many balls with your hippo as you can. You must be constantly drinking while trying to do so until the game is over.
The player with the most balls nominates someone to have three drinks and the player that finished last must also take three drinks.
If the game goes longer than 2 minutes then the game must be started over and everyone must take one drink. If a player gets no balls they must take a shot.
