Those did not look like grapes in the thumbnail.

Naturally ... they aren't thumbnail sized grapes.

If any one of them hit him, they'll be the grapes of wrath.

His wrath. <=)

Plucky little devil, isn't he?

I don't think their sourness would be the main problem for that li'l phox; the trouble with hypertrophied fruits and vegetables is that they usually not very edible, their central parts being decayed and so on. There was an article in IIRC Smithsonian Magazine about giant pumpkins and the work involved in keeping them from self-destructing before they could be hauled away for the giant pumpkin contest. Talk about useless.

Over sized fruits and vegetables have also had a history of being bland, as though the plant can't produce enough sugar fast enough to keep up with growth.

Well... If your Foxy Fellow in his anger could manage to hit the bottom grape it might make a little wine.

Or a little whine.

Exactly.
