All the Piplings are busy except Nok Tok. De Li needs a rock for her garden; Yojojo needs wood to mend his slide; Lau Lau needs to move a stone statue to her art house. Nok Tok offers to help, but he can't lift and carry everything at the same time. When the cheebies arrive, Nok Tok tries to think of a solution to his problem. He watches the cheebies playing: they pretend to be a train and then a plane. This gives Nok Tok an idea - he asks the cheebies to help him, and together they help Nok Tok build his most useful invention ever, the Nara Car. Nok Tok loads everything into the back of his car and delivers it as he promised.
