Does anyone have advice on how to successfully play the last section of comptine d'un autre été l'après?

For piano; I just cannot get the last section down. It's the part that sounds like triplets, but is actually in quartets. If anyone has any advice on how to get the rhythm down, please tell me and I will greatly appreciate it!
