Quoted from Kulky:Also has anyone ever. In the world, got to cowabunga mode? Seems stupidly impossible to get too.
I almost got there once. I came out of Final Battle with everything lit except for the Triple Mondo Jackpot. Then I played Turtle Power MB and Ninja Pizza MB without getting it and then drained while trying to play 4 episodes to re-qualify my multiballs.
I don't really play trying to get Cowabunga because that would be a fools errand. But I think the biggest key is to focus on playing through the episodes and make sure to collect the April Hurry-Ups, especially while in MB. You should be able to play 4 Multiballs + Team Up by the time you play Final Battle so that should give a decent number of opportunities to light and collect it.
What I would like to see is each April Hurry-up getting harder to light (less time before timing out the letters, more hits required, etc.) but then make the scoring more clear (a summary when collecting would be nice, because I believe the rule is "the more things happening, the more it's worth" so then you could have something like: "episode running: 200,000, multiball running: 300,000, APRIL Target hits (while mode running):25,000, etc.) then you would have a clear idea of how to score better in the mode. In addition, and especially if each APRIL hurry-up is harder to start than the last, the second one could be 2X and the third could be 3X (and be the qualifier for Cowabunga).
