Description
SCP-3741 is a large, yellow smiley face balloon, measuring approximately 1 meter in diameter. Its expression is always happy, regardless of the situation.

When a human subject makes eye contact with SCP-3741, they will break out into uncontrollable laughter, no matter the circumstances. This laughter will quickly spread to other individuals in the vicinity, and will continue until the subject looks away from SCP-3741.

Additional testing has revealed that the effects of SCP-3741 are contagious, and can spread to other individuals through physical contact. It is not currently known if SCP-3741 is sapient or capable of communication.

SCP-3741 was discovered in a park in [REDACTED], after reports of a group of people laughing hysterically for no apparent reason. The balloon was quickly retrieved by Foundation personnel, and all witnesses were administered Class-A amnestics.
