However, when the player is preparing to leave, the Hatter and the March Hare offer him to stay for a cup of tea with them. The player agrees and the two friends give him a cup that the Hatter fills with sugar. He realizes that there is more sugar for him and the Hare, and asks the player to pick up their two cups of sugar. Once back with the two cups, the Hatter tells the player that he and Hare can't take their tea without butter and jam, so the Player leaves to find some.

It was then that the pair realize they were busy celebrating their unbirthday before the player arrived.
