When you fight grunty she uses a magnetic spell that you can't avoid...for this attack use 1 gold feather. That should be enough to dodge that attack.......when you try to summon the big blue jinjo do the back side first so that grunty will have a harder time to hurt you then when the back is done go crazy and shoot eggs in the remaining holes...dont freak out when your life meter goes down like a mad traffic jam just keep on shooting!
In order to get unlimited eggs you first find cheato the spell book and once you talk to him go to treasure trove cove and empty the water out of the small pool by the sand castle then go inside and kill the crab.
Once you have done this spell out sgge (eggs spelled backwards) then you should have maximum eggs.
First of all you must go to "Treasure trove cove" and collect the jigsaw from the sand castle. Then go to Banjo's house and stand in front of the fireplace. Now press "C up" and look at the picture of Bottles hanging on the wall and he'll allow you to play his puzzle games.
Press "A" to pick up a jigsaw and again to place it Press "B" to drop the jigsaw you're holding Press "C left" or C right" to turn the pieces (won't be necessary until the third puzzle)
There are seven games in all and you must complete them before you can use their cheat codes. You must do it everytime you start the game =(
The codes are: (Don't use any spaces. I did to make it easy to read) "Bottles bonus one" "Bottles bonus two" "Bottles bonus three" "Bottles bonus four" "Bottles bonus five" "Big bottles bonus" "Wishy washy banjo"
Enter the codes on the sandcastle floor in "Treasure trove cove" to change Banjo's appearance. You have to find out by yourself what the codes do =)
Banjo: Look, Kazooie. It's cheato. Kazooie: Best for him that he have some cheats for us Cheato: Bear and bird has cheato found and a spell they will get. Grunty: No, no, no my spells you mustn't tell. I don't want bear and chicken to play that well. Cheato: Witch is nasty and a cheat she will have no more. Enter CHEAT NOW YOU CAN SEE A NICE ICE KEY WHICH YOU CAN HAVE FOR FREE on sand castle floor. Now bear and bird can get the ice key for free. Banjo: Okay, let's go grab it, Kazooie Kazooie: Finally that book brain told us something cool.
