Squirrel in order to gather more pine cones, constantly jumping on the tree, but there are a lot of difficulties, could you help she to realize her dream ?
The squirrel may encounter difficulties:
1.Stepped on the bad branches will fail.
2.Some branches maybe vacillate to the left and right.
3.Some branches maybe only sustain a few seconds.
4.You can't jump too fast, or you will not way to go.
