S-Chu Ball
An S-Chu Ball is a special type of Poké Ball used for the capture and storage of Electric- or Hedgehog-type Pokémon. They receive very little mention in canon, as few of the Sonichus and Rosechus are ever stored in Balls. An S-Chu Ball appears in Sonichu #0 and Chris claimed that Sonichu and Rosechu can be stored in them in the plot for his Family Guy episode: "Then I break out my two S-Chu Balls, toss them and release Sonichu and Rosechu; more greetings."[1] He also mentioned them in a phone call with Alec Benson Leary.[2]
The S-Chu Balls are often confused with the Sonichu Balls, which hold some relevance to the plot and have a completely different function. Any efforts to distinguish the two are probably too pedantic, as superficially they're the same anyway.
