Mr. Saturn

Mr. Saturns are a race found in EarthBound and Mother 3, and also appear as an item in Super Smash Bros. Melee and Super Smash Bros. Brawl. They are the primary residents in Saturn Valley in both games. Mr. Saturns are known for being very peaceful and quirky, and their very distinct way of speaking. Mr. Saturns are also one of the builders for the Phase Distorter.

In EarthBound
The Mr. Saturn in EarthBound play are large role throughout parts of the game. They were first found to have many of their brethern imprisoned by Master Belch, who used them to do most of the labor in Belch's Factory. They don't have any true forms of amusement, but they offer many of their services for free (with the exception of their store).

Late in the events of EarthBound, Dr. Andonuts and Apple Kid work with them to create multiple Phase Distorters. One was originally for the use of Ness and his friends, but was stolen by Pokey, who apparently also kidnapped a Mr. Saturn as well. The fact that the Mr. Saturn are capable of creating such technology shows that they are very dexterous creatures, despite their very odd dialect and habits.

In Mother 3
The Mr. Saturn in Mother 3 play a significantly smaller role. They have developed a hobby of going "fishing" for birds, laying down to stare at what is above them, and forming totem poles. Various members of the Mr. Saturn have single lines of dialog that don't have any significance to the player whatsoever. When Lucas and company must leave the enclosed Saturn Valley, the Mr. Saturn let them leave via tons of "birdies" in a cage. One of them asks Lucas for his Courage Badge and holds onto it for a long duration of Chapter 7.

Later, right before Lucas approaches the second-to-last needle, a hooded Mr. Saturn, presumably the one that took the Courage Badge, gives Lucas the Franklin Badge, an essential item for confronting the Masked Man. Past that, the Mr. Saturn are only seen again in the credits.

In Super Smash Bros.
As an item, they simply amble around, being able to be thrown at other fighters for some damage. They also have their own trophy in both Melee and Brawl.

Dialect
Mr. Saturns seem to speak the English language, but with their own twist to it. The words they speak that appear in the text boxes have their own font. It is unknown if this stands for an unheard accent or not. They also use words like "Kay-o", "Boing", "Zoom", or "Dakota" at the end of sentences. Mr. Saturns also use incorrect grammar (according to the English language) using fragments and lacking the word "am".
