The Jealousy Ball is a ball created when Tamama focuses all his jealousy into his hand. Tamama usually uses the Jealousy Ball when his Tamama Impact shows no effect. In episode 58, Tamama originally used the Jealousy Ball as a way to beat Paul, however Tamama realized he could only use the Jealousy Ball whenever Keroro or Mois were shown together. And a downside is that whenever they are shown together, Tamama usually misdirect's his attack, and has it hit him instead. Also, if Tamama is focused hard enough, he can control where the Jealousy Ball will land.
