In episode 58, Tamama originally used the Jealousy Ball as a way to beat Paul Moriyama, however Tamama realized he could only use the Jealousy Ball whenever Keroro or Angol Mois were shown together. Another downside is that whenever they are shown together, Tamama usually misdirects his attack, and has it hit him instead. Also, if Tamama is focused hard enough, he can control where the Jealousy Ball will land.
Hyper Jealousy Ball Edit
Hyper Jealousy Ball (超・嫉妬玉 Chō shitto-tama) is an attack featured in Keroro RPG. It is Tamama's special move.
