I’m having a tough time trying to read that, the first part is obviously 「ミスター スパーコル!」 (“misutā supākoru!”/mister sparkle) but the second part is hard to read, I think it says 「ハワー ワリーソ!」(“hawā warīso!”) but it doesn’t make any sense to me. Maybe the ハ is just missing a handakuten and it’s supposed to say “pawā”/power? But idk what the second one is supposed to be. Maybe クリーン (“kurīn”/clean)? But that’s a stretch.
