The Rainbow Bus is a three-story kindergarten bus that accommodates 28 babies, including cribs. This set does not include play figures, which are sold separately. The bus can be unfolded into a fun play area for the babies. The seats transform into a carousel, a swing, a slide, a seesaw, a piano, and a stroller. All babies, including those in cribs, can sit in the carousel and stroller. The swing's ropes can be used as seat belts in the bus. The charming design features weather motifs like suns and moons on the bus and seats. Bus dimensions: 30 x 16 x 13 cm, number of pieces: 7. The bus can be combined with the Sun Castle as well as the sandbox and pool with figures, which are sold separately, to create a nursery that looks like a grand castle. It is also compatible with babies, including those in cribs, which are sold separately.
