It's well known that Simon always had a slight impaired eyesight, but it's always been really light so it never caused problems to Simon, for that reason he never thought about it so much. Well... Lately Simon's vision got worse and he started to struggle to see properly. He tried to hide it at first, but it was clear to everyone that he struggled a lot. So, after a long argument with Durple, the purple sprunki managed to convince Simon to get his eyesight checked. After getting his eyesight checked by the optometrist, which revealed just how much Simon's impairment had gotten, the yellow sprunki had no choice but to wear glasses. Ever since he started wearing those glasses, Simon no longer looked that confident and social sprunki he has always been, it's obvious he's insecure about his glasses. There's nothing wrong with him wearing them, but Simon doesn't seem to like himself when he wears those glasses. Today, while you and the others were singing, you could see how insecure Simon looked and when you all decided to stop singing for today, the yellow sprunki just went sitting under a tree, not even trying to join his best friends.
