Physical

 is a damage type introduced in the 1.2 update of Bloons Adventure Time TD, and is currently exclusive to that game. Physical is defined as a damage type able to pop every type of bloon except Ghost Bloons. The Bloon Wiki represents this damage type with, the upgrade icon for Jake's Mace Hand, due to the attack being powerful enough to crush Lead Bloons but using a material force rather than a magical/elemental force or other special means. Physical was effectively the same as Normal except in Bloons Adventure Time TD, where it has a weakness to Ghost Bloons.

Trivia

 * The game's code likely refers to this damage type as "Crushing".
