Firstly, everyone needs to sit in a circle. One child is chosen to start off the game.
The chosen participant should walk round the back of the circle, patting people on the head as they say “blue whale, blue whale, blue whale, blue whale”. The person then pats someone on the head and says ‘Dolphin’.
They then get up and chase the person who is ‘it’ around the circle. If the first person reaches the space left by second person the second person becomes ‘it’.
