Cooler Mammoth is fought alongside a number of Cooler Leeches. It is weak against Fire. If all Cooler Leeches are killed, Cooler Mammoth will regenerate them. The Cooler Mammoth uses strong physical attacks. The Cooler Leeches can cast Blizzara and buff the Cooler Mammoth with Shell.
Porom should cast Slow on all targets immediately. After slowing down the enemies, the player should put both Palom and Porom on Protect, Shell, and Haste. Since the Cooler Mammoth is weak against fire, the player should make Palom use Fira. The player should focus on using Fira on the Cooler Mammoth only and avoid killing the Cooler Leeches. The easiest way to deal with the Leeches is to have Porom group-castSilence disabling their spells.
If Palom runs out of MP the player should use a Ether on him right away. The player should make Porom focus on using Cura throughout most of the battle and avoid using the TwincastBand in this battle, since it takes a long time to charge.
In the PSP version released as part of Final Fantasy IV: The Complete Collection, the Octo-kraken and its tentacles switches their color scheme with the Cooler Mammoth and its tentacles — the purple Octokraken became red and the red Cooler Mammoth became purple. Both enemies are restored to their proper colors for the iOS release of the game.
