Recommended characters, in the simplest form, are fan characters "recommended" by fans of the series. While Bomby made a cameo appearance in "Insectophobe's Nightmare", recommended characters officially debuted in "Lofty". All but one of the recommended characters in BFDI last made an appearance in the last episode of BFDI.
In BFDIA, a "Top 25" mechanic was used, meaning that the creators used Google Moderator to choose the Top 25 recommended characters from all of the recommended characters according to that.
