Blowfish

Today I went to my swimming lesson, first back after the Easter holidays and I have been moved up a group.

Neo - "Why am I not with Noah anymore?"
Mummy - "Because Noah is in the 'Duck' class and you are in the 'Blowfishes' now"
Neo - "But why am I a blowfish"
Mummy - "Because you are good at swimming"
Neo - "But ducks can swim"
Mummy - "But blowfish can swim under water"
Neo - "What is a blowfish?"
Mummy - "It is like a puffa fish"
Neo - "I like them, they are like spiky balloons"
