Our Japanese is not quite good enough to ascertain the nuances of this dramatic scene, but what we could understand was self-evident anyway. In this ad for Harvest Moon: Waku Waku Animal March, the frog wants the cow to give him a ride like the animals in the game do.
The cow (spoilers!) relents, and the frog gleefully hops on, only to find the ride slow. The cow complains about being out of energy, and the frog cheers him on, telling him to summon his "cow power." Then the frog takes off on a date with Keromi-chan.
In the second part, after the break, the frog and cow decide to make use of Waku Waku Animal March's photo features. Wackiness ensues, culminating with the frog asking the cow to take some "sexy" shots.
And that's why you should buy Harvest Moon: Waku Waku Animal March.
