There is a glitch where if a squirrel is not raging and a green bloon or higher ranked bloon is leaked, the squirrel will rage green instead of purple. So if a bloon leaks or if it throws 50 acorns, it will throw the acorns at bloons as fast as the Super Monkey's Plasma Blast. Only works once placed in the range of a Meerkat Spy.
In the Angry Squirrel Pro description, it says "acrons" instead of "acorns". This is a typographical mistake.
The Angry Squirrel Pro has been nerfed and now requires 50 acorns to be thrown to rage, instead of 20. This was not in effect during Special Agent Pro weekend.
The Angry Squirrel Pro will turn purple when raging instead of green.
