Super clever script. You toy (no pun intended) with our expectations of what the script os getting out. That final panel reveal that its kids playing is just a stroke of genius. The fact that you drop a tint in panel 3 with that "wait, no, wrong one..." line is brilliant writing and also makes great use of the change of dinosaur in the next panel.4/5.
