Hi hi! Ummm are you talking about this gif?
hahaha! He is being Lay - yet again! By that I mean he is being adorably cute again ;) I think the little yellow object is suppose to either light up or make a sound when it’s pressed/hit so Lay was just trying to get it to work but he is obviously failing [or maybe it did work - we just don’t know it] lol
I hope this helped. [If this isn’t the gif you’re talking about then..*goes hides in the corner in embarrassment lol*]
[I don’t own the gif]
