This is my airplane. I figured out how to add a color and texture totally by accident and it turned into what I am calling a sponge like toy for the bath. You did say it was supposed to be like a kids toy 
I am really enjoying this course lots. I am amazed what I can make with just 1 simple cube and a little imagination.
That’s cool! I That’s a great sponge plane. I would totally play with that as a kid
