Yeah, it's supposed to turn the otherwise featureless wall into a mural so you can solve the puzzle. I had the opposite problem in that area, where the psychedelic effect would only last like five seconds, so I'd have to do the puzzle little by little, pausing constantly to lick the frog again. Then, the last time, when I was about to solve it, the psychedelic effect stuck around, so I was in Nazi Germany seeing flowers and grass everywhere.
