Panpour has such a compelling design

She is part of the Elemental monkey trio which through design represents the whole "see no evil, hear no evil, speak no evil" thing
Hers is See no evil

Pansear the fire type is clearly holding his hand to his ear because his hearing is bad
Pansage has his hands around his mouth because he cannot speak

Panpour appears to have her eyes closed but in reality they are open

Her pupils are white
She is blind
