Ok, so in knoddys resort, lots of top players start the radical points, does phantom skateboard, gets the points for radical points, and then puts the guards in the water. Making them get 3 ice creams in just one minute. Although, when I try it, I do the same stuff, except radical points isn't giving me the ice cream. Is there a tutorial on this exact start? Is there a specific thing you have to do?

just keep the textbox open until the ice cream spawns

thank you!
