"A wooden bass whose time in the limelight is up. Holds a grudge against the new bass on the block."
Battle Memory
"As you can plainly see, I am a wooden bass. I'm still in my prime. But ever since the bass below showed up, I've been left to rot in this moldy-smelling attic. I'm filled with so much frustration. I'm gonna turn this frustration into violence and take my stress out on you guys! You're gonna be bawlin' your eyes out!"
— Jealous Bass

The Jealous Bass is a boss in Mother 3. Like its name implies, it is a jealous old bass that was once used by Lucky in the DCMC.


When Lucky started using a new bass, the Jealous Bass was left in Club Titiboo's Attic, despite the fact that the instrument was still usable. Due to its frustration, the Jealous Bass apparently became sentient.

During Chapter 4, Lucas and Boney come across the abandoned bass, who takes its frustration out on the group and attacks, along with a Beaten Drum and a Gently Weeping Guitar. Once the Jealous Bass is defeated, Lucas and Boney can escape the Attic by jumping through the air duct into Lucky's room.


The Jealous Bass is capable of using Hypnosis α, along with a normal attack. For its most notable attack, it can initiate jam sessions with its "bandmates"; each of the instruments attack consecutively, with the Jealous Bass attacking twice. Its battle theme is Rock and Roll (Spicy), which can be changed by the Beaten Drum assisting it.

If Lucas defeats its comrades first, it will fly into a rage, causing its offense to rise. The Bass also resorts to solo jam sessions (a series of multiple strikes) as well.

Its battle sound is Battle Sound 13, which falls under three code numbers: 475 (regular attack) 476 (Smaaaash) and 477 (Miss). It is the only non-Titany enemy in the game (excluding the unused Aeolia's Table) to have this battle sound.


The Jealous Bass is often considered one of the most difficult battles in the game, due to its usage of Hypnosis α and it's jam session attacks. To defeat it, it is recommended to have both Lucas and Boney at level 17+, atleast 1 pencil rocket and several sprinting bombs. Begin the battle witk Pk Love α and a pencil rocket from Boney. This will do enough damage for both the Gently Weeping Guitar and Beaten Drum to be defeated, however due to the Jealous Bass' speed, they will likely preform a jam session before you attack. Once the allies are dead the Jealous Bass will waste a turn flying into rage, use this turn to heal any damage from the jam session. From this point on use Lucas to do PK Love and heal himself and Boney, while Boney uses sprinting bombs or pencil rockets to attack. If the Jealous Bass makes one of the two fall asleep, try to keep them sufficiently healed so they can survive waking up. Do this and with a bit of luck, the Jealous Bass will be no more.

  • Strangely, The Jealous Bass has a weakness to PK Fire, however it is not possible to utilize this as neither Lucas nor Boney can learn PK Fire.
