SCP-999 (full name:The Tickle Monster), is a safe SCP that's known for its adorable appearance.
SCP-999 has a major interest into people that are unhappy or hurt in anyway. People that have depression, after interacting with SCP-999, are totally healed from their problem, also they get a very positive picture about life.
Because SCP-999 is a very playful being, it appears that SCP-999 loves all animals (but especially humans). SCP-999 doesn't eat meat at all, and it even risks its own life for others. It was confirmed that SCP-999 indeed would leap in front of a person to take a bullet inside of it. The creature eats candy and sweets.
