"Kwak was a good friend, and he was always a helping friend. Without him, fun is going to be less fun, and I want him to come back. I know he's not dead but please help me find him before its too late. Last day to find him is on April 4th." - Appaul. Just add yourself. Appaul is sad and he misses his best friend, so please support him.
And this not an April Fools joke, this is serious in the current lore.
