As expected, it is very sour, but a good kind of sour.
After you finish your ice cream, the ice cream truck disappears, and in its place is an eleborate and beautiful dinner table full of tea cakes, cookies, and tea cups. At the table is sitting a man with a top hat and cat ears, a woman with a fish head, and your unicorn friend. "Join us," says the unicorn indicating an empty seat.
Feeling like Alice in wonderland, you sit down for tea, and enjoy an extremely pleasant afternoon with new friends.
And you lived happily ever after: The End.
