Onion

Onion is a major antagonist in Five Nights at Yoshi's.

Appearance
Onion is depicted as a blue animatronic dinosaur with a red and yellow striped part hat with a little fluffy puff on the top. She has orange spines on her head and orange-brown shoes like Yoshi's, except swapped around. She wears a beige bib with the phrase 'EAT NOW' on it, with 'EAT' in a bright purple and 'NOW' in a darker purple. Additionally, she carries a white frosted cupcake with a candle on top, and rainbow sprinkles on cupcake's head, carried on a plate. And yoshi is five nights at sonic's

Personality
Onion likes playing tricks on people, and enjoys to eat as shown by her EAT NOW bib. The most common trick she plays is activating a decoy by stuffing an endo backstage into an Onion suit, which can trick the player into wasting power.

Behavior
Onion starts onstage and is active starting halfway through Night 1. She uses the right door to get into the Office. She appears in the Yoshi Stage, Party Room, Backstage, Window, Right Corner (far away), Kitchen (audio only), and then finally Right Corner (at the door). The rooms she enters is random, sometimes moving forward 2 rooms, other times backtracking 1 room. Unlike Daniel, she will not hide from the blind spot, meaning you can open the door to check if she's gone without the cameras. However, this is not a reliable strategy, as opening the door leaves Onion enough time to jam the door and kill you.

If Onion enters the Backstage and leaves, a decoy has a chance of appearing at the right door. The decoy is meant to fool you, and does not attack the player. If Onion chooses to not go in the Backstage, the decoy will never appear for the rest of the night.

Trivia

 * Onion was originally mean to jump away from the blindspot as well, but this was scrapped.
 * In the demo, the decoy was harder to tell apart from the real thing, leaving fans complaining, some claiming it was a glitch. It was changed to make it more easy to tell in the full game.
 * She's the only female animatronic in the entire crew.
 * Onion's cupcake has a name, Charlie, although it's never mentioned in-game. The name was chosen because it sounded similar to Carl, which was the cupcake's name in FNAF 1 according to some people.
