Toadsworth is such a weird character in the Mario mythos. He was all over the place since his inception in Sunshine like he became a permanent member of the extended Mario cast like Bowser Jr. did. He was in the RPGs, he was all over the Party games, he would at least cameo in Mario Kart. He was poised like he was here to stay, but then he just vanished. Last time he turned up in a non-rerelease/remake was Dream Team in 2013. I only remembered him just now because of him being in the TTYD remake.
