The Spacy Brothers (スペイシー･ブラザース Supeishii Burazaasu) are a trio group composed of Spacytchi, Akaspetchi, and Pipospetchi. They appear in Tamagotchi! (anime) and every one of it's sequel series so far; Tamagotchi! Yume Kira Dream, Tamagotchi! Miracle Friends and GO-GO Tamagotchi!.
The Spacy Brothers are aliens from a different planet called Spacy Land, but they landed on Tamagotchi Planet. They are the only ones from their planet that know about Tamagotchi Planet (except for Himespetchi), and they want to take it over to become kings of it. Spacytchi is the boss of the Spacy Brothers.
