Give an example of something that happens periodically?
An example of something that happens periodically is the presidential inoguration(every 4 years), the weekly news(every week), etc.
PUSH means Pray Until Something Happens. For example you really wanted that new fancy bike for Christmas. You need to Pray Until Something Happens. And when god feels its the right time to give what you wanted to you that's when you will get it. but until then you need to pray until something happens.
the only Pokemon in any game that changes color when something happens, is Arceus. It changes color when you give it a plate of differrent kinds. For example: if you give an Arceus a toxic plate, it will turn purple and become a poison type. If you give an Arceus a splash plate, it will turn blue, and become a water type, etc.
