What are the clear plastic tubes for, that came with the costume?

There are little sleeves on the inside of the truck cab part, just above where the front wheels stick out, that the straws fit into. They help keep the tuck cab sticking outward instead of flopping down.

How do you attach the truck cab to your child’s body? Please help we can’t figure it out!!

Did anyone figure out how to attach the black straps?

Sizes run small or big?

Very big and doesn’t convert easily

I need someone smarter than me to show me how to do the straps on the cab part. How do you secure the straps?

Hi! I don’t know if this helps, but my son put on the straps like you would the straps of a bookbag. That’s the only way that helped me to figure it out
