That being the second level really set the tone for it.

My boyfriend was watching me play and "forced" me to replay it a few more times after that happened. We were both just shocked.

Loved the singing piranha plants, but have to give credit to Rayman Legends who did something similar 12 years ago.

A music theme level isn't the same thing as a level where the monsters are singing and clapping. The piranha plants have lip synced singing and clapping which makes most of the music. When a new plant enters the scene you can here the new voice starting, kill it and that voice dies.

For example, in rayman legends they have music and then spawn monsters with the instruments of the music, but those monsters has nothing to do with the music since the music is a static track, killing them or them spawning doesn't change anything.

Are you...trying to say that they weren't potentially inspired by something else? Because they almost certainly were, whether it was Rayman or something else.

It's okay for them to seek inspiration and for all of their ideas to not be completely original. It's acting cult-ish otherwise.
