So, Starfire wanted her sister Blackfire to know about Robin's adorable weakness and the two girls flew over to where he was. Starfire wasted no time and started tickling his belly, while Blackfire tickled his sides. Robin was overwhelmed with hysterical laughter as he was being mercilessly tickled by two extraterrestrials.
