- "Appears in Temple of Droplets. An ordinary blue Chuchu. Fighting him while Minish-sized is daunting, but just try to avoid that electric attack."
- — Figurine
The Big Blue ChuChu is the mini-boss of the Temple of Droplets, the fourth dungeon in The Legend of Zelda: The Minish Cap. Like the Big Green ChuChu, it is not a giant; it is a regular sized Blue ChuChu, but since Link is Minish-sized during the battle, it appears to be a giant Blue ChuChu.
During this battle, Link must be careful not to touch it as it will electrify him upon impact. The Gust Jar must be used to suck away its base, causing it to collapse under the weight of its own head, similar to the Big Green ChuChu. However, this is difficult, as the Big Blue ChuChu is immune to the Gust Jar while it is electrified. Once it is stunned, strike away at its head with the White Sword. Occasionally, it will jump around the room, like the Big Green ChuChu. Repeat this process several times (depending on how many strikes Link has landed) and the Big Blue ChuChu will be defeated.
