i saw the wiki and it says: Icicle Impale is the fifth and final upgrade of Path 3 for the Ice Monkey in Bloons TD 6. The Ice Monkey's snowballs can now freeze and damage MOAB-class bloons, dealing 50 damage to each and freezing them instead of 2. Frozen MOABs, BFBs, and DDTs move at the base speed of a ZOMG, and frozen ZOMGs are slowed by 50%; BADs can be damaged but will not be freezed or slowed down.

The BAD is immune to any movement-altering effects, except the Workshop's Reverse Motors, Time Stop, and Jake's Butt Push. It will always move with the same speed as a ZOMG except if Jake or a Time Stop slows them down.
Excluding upgrades and abilities that ZOMGs and other MOAB-Class Bloons (excluding the DDT), are immune to, below is a list of all upgrades that the BAD is impervious to:
