Okay, an odd movie subject choice, but this is just driving me mad!

I used to have 2 copy of Thumbelina as a kid, and in one version the toad sang a song when he sat on the swing and sang a song when Thumbelina rejected him and he started crying.

I bought the 1994 version thinking it might be that, and I watched the whole way through, but alas, no toad song.

So I'm thinking a)It might be another version (maybe the 1991 version) or b)It doesn't exist.

Does anyone else remember the toad singing a sad song on a swing? I've tried looking on imdb, but haven't found anything.
