The fifth diary entry can be read once you buy the car. The picture features Spud in a paper car, dreaming of driving a red racer car that, curiously, seem to have cat eyes and a tail.
Everyone likes the little bear I made.
He's pretty fun.
The entry mentions a bear, which probably is a remain from some translation engine; bear in Japanese is kuma, car in Japanese is kuruma. The Japanese version also contains a pun! To ride in Japanese is nori, and "merrily" is norinori.
When I made the car toy, they rode it merrily.
I wonder what kind of fun stuff they're thinking about...
