I've only ever seen or played the first game. I know it's for small children and all but a lot of stuff in it doesn't make a lot of sense. Like why do the sharks want the kelp seeds? Since when do sharks eat kelp? And if Freddi's grandmother's seeds aren't found the other fish are all going to die of starvation because that's all they ever eat, although Grandma Grouper gives her a peanut butter and jellyfish sandwich at the start of the game. But then again peanut butter and jelly usually have kelp in them to thicken and keep the ingredients from separating. And then there's that singing crab who wants his fishing pole. Okay the crab wants an item used to catch, kill and eat fish, and his friends are fish. Mmmoh-kay...
But it was kind of cool how nearly everything you clicked on would do something funny or weird.
