Trivia

 * In BTD4 and BTD4 expansion, the boomerangs, glaives, or light sabers disappear about 2/3 of the way back if the game is on Fast Forward. This is because,oddly enough, the boomerangs themselves do not move faster on Fast Forward!
 * This does not happen on the iPhone/iPod touch version.
 * The Boomerang Thrower is the only tower with a purple outline in BTD4.
 * Apparently, Super Monkey can throw boomerangs too as in Bloons Super Monkey, a boomerang is a purchasable upgrade.
 * There is a feature in Bloons Super Monkey where when Super Monkey is throwing a boomerang, it will continue behind him after it reaches the point where it would normally be caught. It is unknown if this is a bug or not.
