is it banjo's move where he goes into his pack and hops around (I think it's called sack pack, i'm not exactly sure)?

Wow what a great guess but sadly, no.

1. Reminds me of another Rare game for the N64.
2. RUN AS FAST AS YOU CAN
3. Or should I say... hop as fast as you can?
4. I used to be useful... not so much anymore.
5. People still collect me for some reason

I'm actually getting worried that my memory is playing tricks on me... If so then half of those clues are irrelevant.

Mine or Brawl Noob's was a great guess?

Well my other guess is Yumblie...

Jinjos

8. I am a box-like object.

I ran out of ideas.

mega glowbo? stop n' swop items? if it's not either of these i'm stumped.

You're close. Think think think. What's a box like object that hold something and moves around. It gives you a better bird somehow.

A box that holds springy step shoes?

BK cartridge
1)bk is another rare game
2)3) run or hop because it runs faster when you get near it
4)?
5)it isnt amazing what they giveyou but they are still collected
6)they egg thats one one of them was from stop n swap which didnt wrk
7) one of em gives kazooie a new move i think

The cartridge was correct. I was kind of vague with that one.
