Trivia

 * The almanac references how Puff-shroom is often used as a bite blocker for No Sunflower strategies.
 * Puff-shroom is referred to as a girl, because she's voiced by Ellie Goulding in (English) and male voice is, Sanjay Keni - Arshad Warsi (Dubbing artist of Oggy and the Cockroaches) in (Hindi) unlike in the other games.
 * This is probably because if it wasn't changed that way, Girl Power! would be nearly impossible in night time.
