Zerby Carrier

While out for a drive, Zack, Lily, Rose and Goldie all hit the same rock and they all get flat tires. Rex brings his trailer out to carry them back to Mika's Shop so they can get fixed, but the trailer isn't big enough to fit 4 broken Zerbies. With a rainstorm coming in they have to figure out a way they can all get back to Zerby Town. They try getting on the trailer facing forwards, but that only fits 2 Zerbies. They try sideways, which works a little better, but still only fits 3 of the 4. They try piling on but they just end up falling off when Rex starts to move. Even using sticks to make the trailer bigger doesn't work. Finally, Zack gets the idea that if everyone give him their broken tires and he gives the others his working ones, then he can ride the trailer with 4 broken tires and the others can drive home.
