Happy Tree Friends Flippy

Flippy, my favourite character in the Happy Tree Friends universe (well at least the good Flippy. His evil side ranks 5 or 6 in my list) this time in 7 different emotions and activities!

Flippy is a Special Forces Soldier in the army. He achieved a very high kill-death ratio with an approximately 12:1 ratio. He is a bipolar soldier. His good side is considered one of the kindest in the universe. When he flips out, things turns out for the worse for everyone caught in his sights. Known methods to wake him up including water, Flaky's screams (only works rarely), and to wait until he calms down. Killing him will also stop his rampage but it is not recommended as most will not stand a chance againts his evil side even from 20 feet away.

P.S. Can anyone help perplexed Flippy too solve his equation???
