What if Wally has synesthesia??

So, I was scrolling through Tumblr, and I saw this post of Wally being paired with a reader with visual-gustatory synesthesia, and I realized: What if that's the reason Wally stares at us so much?? Like?? Idk if it's visual-gustatory exactly, and idk much about how it works, but I saw that someone had theorized that him staring at us and breaking the fourth wall is a threat because he eats through staring at something, and what if he's actually just admiring the taste he gets in his mouth when he looks at the viewer?? Or even the cameras?? What do y'all think??
