Encourage
The "Cliff of Ten Thousand Power" is where you go if you want to be encouraged.
If you can get to the top of the cliff, it will use its "ten thousand power" to encourage you.

はげ
None
When you get there, it does encourage you. The cliff says "Hey, I encourage you to buy a ray (れい) gun."
A cliff is encouraging you to buy a ray gun for some reason. This is not the encouragement you expected, but it is encouragement nonetheless. You go back down the cliff and immediately buy a ray gun.
