That grin isn't for nothing.
It means he already knows something you don't.
El Toad Pepe showed up already mid-smirk — bright red shirt, yellow overall straps, and a look that says he's known where this was going the entire time. No dialogue needed. The face does all the talking.
That's really the whole appeal: a puppet with more aura in one sideways glance than most characters get in a full scene. People started sharing it, captioning it, reacting with it — the way any good "he already knows" face spreads online.
$TOAD exists to put that exact grin on-chain — same energy, same confidence, same refusal to explain the punchline.
