The Bigger They Are (BTD Battles)

Not to be confused with the quest of the same name on Bloons Monkey City.

The Bigger They Are is an achievement in Bloons TD Battles. To get it, the player has to beat another player with a higher battle score than the player. For example, player A has 500 and their opponent has 550 and player A beats them. It is the opposite of What Did You Expect.
