See the model
Two rows of blue windows, a rounded front and a long red body make this little bus ready for a busy route. Two wheeled bases support the lower, longer shape.

Match the shape, size and colour to the parts pictures. A stud is a round bump on top. Count rows and columns from one edge.
New pieces keep their full colour. Earlier pieces are lighter. Keep the front of the model facing you unless a step says to turn it.
Gather all the pieces first, then take each step at your own pace. Help your child press pieces together and lift removable parts gently.
The bus uses two matching wheeled bases. Each base includes its attached wheels and counts as one piece.
The windows are solid blue bricks. The roof and doors are fixed.
This bus has not been sized for the car-wash tunnel.
Gather pieces
Colours show the pictured version. Cream represents Tan and brown represents Reddish Brown. Match shapes and quantities first; other colour choices have not been checked for this edition.
