Per 
The emotion graph
Item #: SCP-XXXX
Object Class: Keter
Special Containment Procedures: SCP-XXXX must be contained in a non-negative emotions area with a 5km ratio, every hour there should be a stress check to indicate if the person should be escorted of the area or be directed to a psychologist.
In order to know the specific level of sadness or stress any organism shouldn't have it was created an emotion graph with its unit being Negative-points (Np).
Every act resembeling negativity will be added as a point like crying, getting in an argue/fight or simply a sad face; the opposit happens with positive acts like smiling, hugging, kissing, playing or laughing.
Description: SCP-XXXX is a truck sized dark blob. It has slime like physical properties including shape-shifting. SCP-XXXX is known for despizing any negative emotions and forcing positivity in any living being to the point where it can force plants to be positive and happy. Research on SCP-XXXX have shown that infact the entitie can detect the level of stress and sadness on living beings, however it is not known if it's achived by thelepatical abilities or by just looking at some sort of signal. Due to its physical properties SCP-XXXX will haunt and kill anyone within a 5km ratio that isn't happy or positive by materealizing right behind them and ingesting them. It is unknown if SCP-XXXX actually seeks sadness and feds of it or if it wants to erradicate it from the globe and make everyone happy. Since the entitie has the ability to shape-shift and meterealize within the area it is frequently common to occur containement breaches so in order for SCP-XXXX not going after any other person near by it has to be isolated in an island located in █████.
