FROG JUMP
It's a repeat-the-sequence game.
At the beginning of each round, music plays as Watawatatchi dances back and forth while holding two lily pads with frogs on them. Suddenly, a frog hops off one of the lily pads. Then another frog hops off. (Sometimes it's only 2 frogs, but sometimes it's a lot.) Finally, a Japanese word appears on the screen. (It says "catch".)
I hope you were paying attention to what just happened; because now you have to press the A (left) and B (middle) buttons in the order that the frogs hopped off the lily pads. Press the A (left) button for left side; the B (middle) button for right side. Hint: wait for the Japanese catch word to appear on the screen before you press any buttons.
