I've found this (warming up before the lesson)
To begin to toboggan
First buy a toboggan,
But do not buy too big toboggan,
Too big toboggan is too big toboggan
To buy to begin to toboggan)))

Thank you so much, Nigel!
But toboggan - it's mostly about sport, am I right? Or it is - bobsleigh?...???

 A traditional toboggan is made from wood, although other substances can be used as well. No runners are fitted onto a toboggan-the toboggan is itself a giant runner. Toboggans can be dragged across the ground by people, dogs, or other livestock, and appear to have originated in Canada.

A Sledge or sled  is mounted on low runners drawn by work animals, such as horses or dogs, and used for transporting loads across ice, snow, and rough ground.

In the UK generally we only use the word sledge for all forms of these types of things.  No one here really talks about having a toboggan.
