Interpreting a toddler

We were asking Colby today if he wanted to go to the big bookstore in town and he asked which one and Misty told him it was the one with the big Thomas the Train set and he said the one with the big alligator in it. We didn’t know what he was talking about and said he must be thinking of another place. He said no, the alligator, you know the thing that helps you go up and down. Misty said you mean escalator the moving steps. Colby said yea. I thought it was an alligator.
