Dinosaurs on the Stairs?

Mini Muffin's imagination has been flourishing lately.  She's doing really well at independent, creative play, and loves pretending to be various animals and creatures.  Frogs, puppies, tigers and dinosaurs feature heavily, as do Anna and Elsa from Frozen of course!

Her imagination has also been encroaching on dinner time recently.  One of her new dinner procrastination techniques is seeing a "scary dinosaur", and either running away, or being so distracted by it that she can't/won't eat.  I love her use of imagination and certainly don't want to interrupt it, but I also need her to eat dinner (and stop distracting her brother from his dinner with screams, roars, and the like!)... What to do?

One evening I found a solution that's working perfectly (for now) - I turned to the dinosaur and gave it a serious talk.  I explained that Mini Muffin was having dinner, and that he needed to leave her alone so she could eat her healthy supper and grow big and strong.  I told the dinosaur that if he couldn't do that, he'd have to go sit on the step. (Background: When Mini Muffin is struggling with big emotions we sit with her on the step and take deep breaths and talk until we can resume normal play.)  The dinosaur was even talking back a bit - cheeky guy! So, I sent him to the step until dinner was over. 

Can you spot the dinosaur?

Mini Muffin looked at the step regularly, and we talked about how even dinosaurs have to behave at supper time.  After dinner, the dinosaur didn't seem to be an issue anymore, though every couple of days I find myself sending some creature or another to sit on the stairs during meals, snacks or at nap time.  Things you never thought you'd find yourself doing...
