This song got periodically been stuck in my head for 20+ years, despite the fact that I surely hadn't heard it since 1998. When the game came out, the idea that there would be over a minute of animation and an original song just hidden behind a non-essential hot spot was like an audaciously opulent use of FMV. I don't think Humongous ever did anything quite like that again, but it was cool.
When my kids first played Putt-Putt I was interested to see what they would think about that part. They had been playing for about ten minutes before they clicked on the 'Topiary Creatures', and then kind of sat there dumbfounded as the song played. At the end, my seven-year old announced "Ok, we are NEVER clicking on that EVER AGAIN".
But by the second or third playthrough they willingly clicked on it several times in a row, and since then we have sung the song while walking to the park, so its power as an ear-worm is enduring. 🥲
