When Alfie had foolishly took a sip from the fountain, he had drunk a handful of water from the small bowl, which meant that he was going to shrink!
Alfie began to dwindle down in size. Everything around him seems to get bigger, when in reality, it was him who was getting smaller.
Also, at the same time, Alfie noticed that his clothes were getting baggy and loosening.
(Of course, Alfie had failed to take into account that the effects of the fountain's water had no effect on clothing.)
"Oh my!" Alfie Exclaimed as he got smaller and smaller. "I'm shrinking!"
Indeed.
Alfie shrunk down to the size of a doll.
And almost as quickly as the shrinking started, it stopped.
Alfie climbed outta his now enormous clothes, naked as the day he was born. He clambered onto the ground, and stared at the fountain. It looked as huge as a building.
