So...how does everyone move around with no arms and no legs? They're, you know, fruit.
Maybe they have small muscles that they don't use very often because it is very hard to work them.
In Exploding Orange, shortly after Kiwi explodes, we hear footsteps as Passion and Pear run into the room. It's likely a case of Invisible Anatomy.
How are fruits related? Grapefruit is shown to have a sister, a second cousin, a grandpa, and a nephew, and Red and Golden Delicious are cousins. Fruits from the same tree are probably related, but what make them a parent, cousin, sibling, etc.?
Umm... I suppose that, unless the plants are self-pollinating, two pollinating plants who produce seeds can be considered parents.
How does Orange stay alive for so long? Surely he would have been eaten or gone rotten or something?
