The cartoon boy might be picking his nose because he's not been taught better manners. Or it could be a comical way for the cartoon to create a funny moment.
It could show a cute and confused boy standing in front of a closet, not sure which clothes to choose.
Maybe it shows that the boy is observant and notices even the tiniest of treasures. Or it might just be a random act to add some charm to the cartoon.
The cartoon could depict the boy in a focused state, using all his strength to lift the weights from the floor. There might be expressions of effort and maybe even some encouraging words or thoughts shown in speech bubbles.
Maybe it's just for some comical or attention-grabbing effect. Cartoons sometimes do odd things for entertainment.

The scene could be heartwarming, with the boy gently reaching out to the dog with a big smile on his face.
