Three Fruit

Han Sen tried a lot of things, but he still couldn't get the crystal shoe off his foot. That shoe seemed to have been permanently attached to him, and he couldn't even get the thing to wiggle.

After a short while, a sand mouse managed to cross the entire fluorescent lake and reached the island.

The island was very small, around two thousand square feet in total area, and there was a fruit tree growing in the middle of the island.

The fruit tree wasn't very tall, and it looked like an ordinary pear tree. Despite the fact that it was around ten feet tall, there were only three pieces of fruit hanging on it. Perhaps some of the fruit had already been taken.

One of the pears was green, one was red, and the third one was yellow. It was strange how different all the pieces of fruit looked from each other.

If the green pear hadn't matured yet, then what about the red pear and the yellow pear? Which one had matured?
