"I want to forget the little nuts"
Seems like the translation has been fixed in your link, it no longer says nuts.
Also the original translation you quoted had many mistakes in it, for example this:

You wave your chestnut like a flag, little squirrel

The lyrics at that point is 旗振る子リス which means Little squirrel waving a flag transliterated, and nothing suggesting about waving chestnuts. In the corrected version on the site by Ohseki, it is now translated as Little squirrel, waving your flag.
I'm pretty sure that it was just a bad translation overall.
