David’s request was quite open and merely asked for aeroplanes. Jack decided to draw 3 baddy planes (red ones), one of which has been shot down. The 3 goody planes on the left (all with forcefields) are each flown by Mr Pricklepants (his toy hedgehog), Green the Dinosaur (his toy dinosaur) and Beebee (his toy Bumblebee). I think I have explained it correctly!
