a question to the 80's generation

[lilac_elf]

I'm hoping someone can help me figure something out. I was watching 'Rainbow Brite' on YouTube and I had something of a cartoon flashback. Was there a longer episode or a 2nd movie? I know of the 'Star Stealer' movie but this wasn't it.

I remember there was evil... thing trapped in a bottle. And they RB team had to use something to travel along a river.

If I'm making sense to anyone please PLEASE help me!
