The DoriTama Rainbow (ドリたまレインボー Doritama Reinbō) is a traveling train created by Mametchi that has the ability to travel to both Tamagotchi Town and Dream Town after they seperated back from DoriTama Town. It was only seen in episode 50 of GO-GO Tamagotchi, making it the shortest living object in the series.
The DoriTama Rainbow is mainly yellow and orange. It has five horizontal stripes on its sides that are light, light orange, light yellow, green, and blue. There is a large blue 'M' where the first door on the train is (which likely stands for Mametchi). There is a large blue fin-like decoration on the top of train near the front, and an orange fin-like decoration attached to the back.
