Senna Bird

Senna Bird (or Ayrton Senna) is a playable bird exclusive to Angry Birds Go! based on the late Brazilian three-times Formula One champion Ayrton Senna. He functions the same way as Chuck in Angry Birds Go!, and has the same power as him in that game. Senna can wear his iconic yellow-and-green helmet if you win 41 races while playing as him.

He was added in 2015 but he is no longer playable in v2.0.

Gameplay
Senna Bird's ability is the same as Chuck's but sightly faster. It may not seem as if Senna Bird is progressing that quickly when the player activates his ability but actually slows down the time, which is why it seems as if he is not progressing in speed.

Trivia

 * It's unknown why he was removed in the v2.0 update.
 * Chronicler Pig was an old sprite model of Senna Bird in v1.4.0. See more here.
 * Ayrton Senna is the sixth bird to be based on a real person, the first three being the Developer Birds (based on Peter Vesterbacka, Jaako Iisalo and Serdar Soganci), Freddie Mercury being the fourth and Slash being the fifth.
 * Senna is the second bird to have his character modeled on Chuck, the first being Freddie Mercury. They are also the only birds made in tribute to deceased people (Freddie died in 1991 and Senna died in 1994).
 * The reason why you have to win 41 races as Senna to get his helmet is because this is the same number of victories the real Ayrton Senna had during his Formula One career.
 * If you have a helmet version of it then the NPC will be a clone but without a helmet. This also happens if you have another racer.
