you get 40 gs and go to the therd part of bikini bottom and go to bubble buddy and he'll give it to you try it (because i'm not sure)

go to the therd part of bikini bottom and go to bubble buddy and he'll give it to you;)i'm pretty sure!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

wheres the third part?

you get enough golden spatulas beat robot patrick and go to the third part of bikini
bottom press the R1 button and there a cruise bubble you dont need to talk to bubble buddy
if you already know how to use it.

that did not work!!!!!

you will have to beat robo. patrick (Bikini Bottom 2 After Robot Sandy).once you beat him
you will have Bikini Bottom 3. go to Bikini Bottom 1 And go to Downtown Bikini Bottom (at
the sea needle). when you get there go to i Don't remember What door It's in Either north
east or west you will see on the broken part a cube With a balloon on it press it by
pressing L1 .get Sandy and there will be a platform. there will be a golden spatula And
then Destroy the G - Love. press the button and you will open the south door.

The one before this I told you how to do the mission come back with the cruise bubble.To
get the power,defeat robot patrick,then you press the button "L1".To get bikini bottom
part 2 beat robot Sandy (get 15 golden spatulas).To get Bikini bottom part 3 defeat robot
Patrick(get in Bikini Bottom part 2 and get 40 golden spatulas).

I did all of that but someone has to teach it to u. Who?

Bubble buddy teaches you the cruise bubble, just like he taught you the bowling move.
