There are a few mascots mentioned in Speak. The first mascot mentioned is, of course, the Trojan. Since the Trojan War was presumably fought over an adulterous alliance between Paris (a Trojan prince) and Helen (wife of Menelaus, king of Sparta), Merryweather High officials decide that the school mascot will be the Blue Devils.
The next mascot is the Tiger. However, the Ecology Club argues that it is a grave disrespect to make an endangered animal the school mascot. The Ecology Club's protests eventually lead to a vote for a new mascot. The school has a difficult time choosing a new mascot to replace the Tiger, however. Melinda tells us that some initial ideas were considered but that none of them were suitable. For example, "Buccaneers" represent pirates who promoted violence and discrimination against women. Meanwhile, "Warriors" is an insult to Native Americans, and "Overbearing Eurocentric Patriarchs" is too controversial to suggest.
The choices eventually come down to four: the Wombat, Bee, Hilltopper, and Iceberg. The Wombat wins the most votes, and everyone thinks that the next school mascot has been decided. However, the Principal decides against the choice. He chooses the Hornet instead, claiming that hornets better represent the values of Merryweather High. Additionally, the Principal argued that the Wombat costume would cost too much, taking away from the prom budget. Seniors support the Hornet choice because they do not want their prom location to be moved from the Holiday Inn Ballroom to the school gymnasium.
The students are only able to call themselves the Hornets for a short time before controversy begins again. The PTA starts a petition to change the school mascot after students begin singing about "horny hornets" and performing the sexy "Hornet Hustle" dance. The student council fights back with a counterpetition, asking for stability and consistency in the choice of mascots. In the end, the Hornet stays as the school mascot; no mention is made of ever changing it.
