A green frog is sitting on a lily pad on one side of the pond. A brown frog is sitting on a lily pad on the other side of the pond.

The frogs want to swap places without getting wet.

There are three more lily pads for them to jump on.

Each frog takes a turn to jump one lily pad closer to the other side.

They can jump over each other if there's a space to land on. They can't jump backwards.

How did they swap places?
