The Chocolate Kamehameha is a combination of the Chocolate Beam and the Kamehameha used by Majuub. When he shoots a Kamehameha to his target, it changes the victim into whatever he wants it to be, usually chocolate. Majuub tried to defeat Super Baby Vegeta with this technique, but the Tuffle parasite countered with his own blast, hitting the blast back at Majuub and turning him into chocolate. Baby Vegeta then devours him.
The blast is not seen in the Budokai Tenkaichi series. However, it is replaced by the Chocolate Beam. Majuub uses the attack with his finger tip, since he lacks an antenna.
