DK Country Tropical Freeze -- That last boss though!

My right thumb . . . HURTS!  Hours later, it still feels like all the blood has been squished out of it repeatedly. I hate to admit this, but, I can't beat that last boss in Donkey Kong Country Tropical Freeze. I'm out of money in game and I can't afford to buy more invincibility potions. I've played the level at least 40-50 times so far. I . . . can't . . . beat . . . it.  WHAT?!

Blow your evil horn, Walrus King . . . you are victorious . . . for the moment

I know what I need to do to overcome this level, but I really really don't want to do it.  sigh.  Funky Kong has a shop and he sells items in exchange for coins that you collect while playing.  For Boss fights, the best item you'll want to buy is the invincibility potion. I believe it might be the most expensive item in the shop at 15 coins for one.

Delicious Banana Juice!  Why do you have to be so expensive?

I fully believe the designers made this last fight so difficult because they knew you'd need these potions to beat it.  It's an absolutely unforgiving fight where you have very small hitboxes to deal with. I've beat all the other bosses, but this guy is wayyyyyy tougher than all the others, and I mean, he should be, but WHAT IS HAPPENING TO ME?! Why can't I kill this guy?!

I've battled through an underwater nightmare with a angry octopus.

He was really really angry! I've survived a myriad of maze-like minecart tracks. 

So maze-like! I've even punched a purple popsicle loving polar bear in the face.

. . . and boy did it it feel good! But this final boss is absolutely the stuff of nightmares for me.  I think it's going to drive me crazy until I beat it. Up to this point, most levels I could figure out and get past in 15-20 minutes. It's a seriously great game (as I've already said in my previous posts). BUT THIS?!?!

I just need to beat that final boss. *cries*

Can I get some well wishes?  Also, can I get some ice for my thumb?

Happy Dueling!
