In Freeplay Mode (Round 86+) bloons move faster each round. This can be observed at Round 150 in a regular game, as MOABs will begin to "drift" around corners due to their high speed (by then, MOABs are about as fast as Pinks). By round 1336, Rainbows would move across the entire track in only a couple of frames, often skipping PAST SPACTORY SPIKES.
