By standing right in the middle of the gap in a sliding wall, it will push you along. It turns out it can actually push you through other sliding walls! Any colour of sliding wall can push you, and you can clip through any colour. There's no point clipping through a yellow wall though since you can go through them normally.
This isn't very difficult to do and might actually be useful for speedruns!

In this video I collect 145 coins in The Secret of Battle Fort. This is the maximum amount of coins possible.
Previously, 97 coins was the thought to be the maximum possible, and had stood as the record since 2009 (http://cyberscore.me.uk/chart/54441). That chart was only added in 2009 though, and 97 will have been the record since the games release as there are no tricks or anything. Then on 27/08/16, I discovered red block coin duplication (https://twitter.com/Really_Tall/status/769525511240478720, https://twitter.com/Really_Tall/status/769531823420473344). This works by destroying a block with a punch, kick, ground pound, etc, on the same frame its blown up by a bob-omb. The trick also works if two bob-ombs blow up a block on the same frame, but that isnt useful in Battle Fort. There are 19 blocks each containing 3 coins in Battle Fort, and the glitch gets you an extra 3 coins from each of them. However 3 of the blocks are too far away for bob-ombs to reach them. So thats 16 blocks, so 48 extra coins, bringing the total from 97 to 145.
Most of the video should be self-explanatory: I collect the coins and use the duplication glitch on the 16 blocks its possible on. There are 3 bob-ombs in the course and they each respawn infinitely.
If the bob-ombs fuses lasted longer an additional 9 coins would be obtainable, bringing the total up to 154. Being able to enter Battle Fort as Yoshi would previously have increased the coin total by turning the goombas into eggs and doing some combos, but now with the duplication glitch Yoshi wouldnt even be close to improving it, since he cant be used for the glitch.
This glitch can be done on any version, so 145 is the max on all versions.
Getting 145 coins will probably never be done in real-time, as each duplication is frame-prefect (at 30fps) and there are 16 of them. However the trick is possible, and with only 1 attempt at the stage I managed to get 100 coins on console. Ill try to improve this more and see what I can get.")
