Muddy Puddles

 is an Expert Map in Bloons TD 6. It is one of 2 Expert Maps to be introduced on initial release, and was one of the first 21 original BTD6 maps introduced on initial release.

Overview
This is a challenging track featuring a swampy theme. Bloons come out the four vertical paths, alternating each round. Bloons will start from the top of a certain vertical path and then move their way towards the bottom of the map.

Starting from Round 1, bloons will start from the leftmost path. Each consecutive round will alternate lanes towards the rightmost path. Once the rightmost path is reached, the next round will reverse back towards the leftmost path. The pattern reverses yet again once the leftmost path is reached, and so on.

There are also several marshes of water on the map to place water towers such as Monkey Buccaneers and Monkey Subs.

Trivia

 * Prior to Version 9.0, the track will go as follows: "Every fourth round from Round 1 (i.e. Rounds 1, 5, 9, etc) will appear on the leftmost path, while every fourth round for alternating rounds will appear on their respective other path (i.e. Rounds 2, 6, 10, etc will appear on the second path; Rounds 3, 7, 11, etc will appear on the third path; and Rounds 4, 8, 12, etc will appear on the fourth path)."
 * Muddy Puddles C.H.I.M.P.S. was first beaten by the YouTuber ISAB (ISuckAtBattles) on 2019-03-17 (v9.0). Ever since, it was made easier to complete the map on C.H.I.M.P.S. to the point where it has been possible to beat with a Black Border and quickly completed on Co-Op Mode by Shwax and three other players.
