Extra Spin Badges

[RandomYoshi]

Glitch Name (you can make it up): Extra Spin Badges
Glitch Description (what happens during the glitch): This isn't exactly a glitch, but it's still a problem. Even after you get the Spin Badge once, you can keep defeating the Green Coconutter over and over again to get more Spin Badges. There's no way to drop the extra ones, so they clog up your inventory. I've had this problem when looking for the Green Coconutter card, so now I have 2 Spin Badges. I've heard that a few other people have the same problem. They should be droppable if you have more than one Spin Badge.
How to activate the glitch (please be detailed and specific): Even after you get the Spin Badge once, you can keep defeating the Green Coconutter over and over again to get more Spin Badges.
Where the glitch occurs (if applicable)(please give the exact map name): Koopa Island
How many players are required to make the glitch occur (if applicable): 1
How many NPCs are required to make the glitch occur (if applicable): 1 (Coconutter)
Why you believe the glitch may occur (if applicable): Because you collect too many. D'oh.
Possible ways to fix the glitch (if known): Make it so you can drop your Spin Badges if you have more than one in your Inventory.
Is this glitch reproducible: Yes.
Screenshot (if you have one): None because I'm lazy.

Just Put them in your bank and discard the item from there

That worked, thanks!

We created the Throw Away item feature in the bank for the purpose of getting rid of items that you cannot drop, trade, or sell, such as the Spin Badge.
