Editing Elder Shrooboid

Prior to the encounter, the Elder Shrooboid captured [[Toadbert]] and [[Kylie Koopa]], stealing the [[Toad (species)|Toad's]] [[Cobalt Star]] shard. When the Mario Bros. arrive at the top of the shrine, Toadbert tries to reveal that the Cobalt Star was meant to trap [[Elder Princess Shroob]] inside, having Mario rub off the dirt on his strange sketch that he had made awhile beforehand to reveal two Princesses. He and Kylie Koopa are then turned into purple [[Shroob mushroom]]s by the Elder Shrooboid. Hoping to gather all the shards and awaken its leader, the Elder Shrooboid then attacks the Mario Bros. and their younger selves. Defeating the Elder Shrooboid rewards the Bros. with the fifth Cobalt Star shard and access to [[Shroob Castle]].

The Elder Shrooboid's spikes normally make it immune to any jump-based attacks and [[Bros. Item]]s, and it takes critical damage from the [[Ice Flower]]. Its first attack involves trapping Mario and Luigi in crystals, similar to [[Shroid]]s, and then grabbing a ball and chain. The Bros. must [[jump]] to break their crystal prisons and dodge the ball and chain as it spins towards them; the spinning eventually causes the Shrooboid to become dizzy, making it drop the ball and fall over. It then gets up again, screams in a rage, and angrily knocks the ball at either of the Mario Bros., while lunging head first into the other brother; the metallic ball will have either an "M" (for Mario) or an "L" (for Luigi) to represent its target. Both Bros. must jump to dodge the attacks.

The Elder Shrooboid can also perform a spin attack similar to the Junior Shrooboid, which the Baby Mario Bros. must counter with their [[hammer]]s; the Elder Shrooboid continues trying to spin into the Bros. pairs repeatedly, requiring multiple counterattacks. The Elder Shrooboid can also throw [[fireball]]s much like [[Blazing Shroob]]s, and may shoot two fireballs at once; these can be dodged with well-timed jumps.

If attacked, the Elder Shrooboid will create a [[Spike Ball|spiked ball]] to throw towards the Mario Bros.; the ball circles around them, moving faster with each orbit, until it closes in on one of the Bros. to strike. The ball can be deflected with the hammer, and may poison the target in addition to damaging them if it hits. Successfully countering sends the spiked ball flying into the air, causing the Elder Shrooboid to gasp and fall over from shock; in this state, it is vulnerable to jump attacks, and its defense is lowered.

After seemingly defeating the Elder Shrooboid, it starts to shrink into nothingness, but then instantly grows to about twice its size and resumes the fight. In this state, its attacks are faster and more powerful, and the objects it uses are much bigger as well. Additionally, after becoming gigantic, the Elder Shrooboid pulls a [[Shroob saucer]] from its mouth; the saucer counts down from four turns before unleashing a massive energy blast, similar to the one encountered in the scripted battle against the Shroobs near the beginning of the game. Similar to that instance, the Mario Bros. automatically lose if the countdown reaches zero, but this time it is an instant [[Game Over]].<ref>Hill Cat (October 21, 2021). [https://www.youtube.com/watch?v=JB6RRyo42ng Mario and Luigi: Partners in Time Star Shrine Game Over Screen] </ref> Unlike that instance, the Mario Bros. can deflect the Elder Shrooboid's spiked balls at the Shroob saucer to reset the counter.

In the North American version of the game, the Shroob saucer changes position in the air during the battle, flying above either the Shrooboid or the Mario Bros.; if Baby Mario deflects a spiked ball, it flies over the Elder Shrooboid, and when Baby Luigi deflects the ball, the spiked weapon flies over the Bros., and the saucer thus changes the character required to reset its counter each time it moves. In all other versions, the spiked ball always goes up and the Shroob saucer always stays above the Bros., making it much easier to hit.
