海啸瓶 is an accessory belonging to the same family as the 云朵瓶. It does the same thing as all others, allowing a double jump. However, the Tsunami in a Bottle's double jump height is marginally greater than that of the Cloud in a Bottle. Additionally, instead of a cloud, this version has a burst of water as the effect from double jumping. It can be found in 铁 and 木匣s.
Reaching two blocks further than the Cloud in a Bottle, the Tsunami in a Bottle comes just one block short of the 暴雪瓶's maximum jump height, yet lacks the speed boost function that Blizzard and those greater than it share.
- It is the only "double jump bottle" item that cannot be combined with the 闪亮红气球 since instead it is combined with the Balloon Pufferfish. Perhaps for this reason, the combined item doesn't follow the convention of the other accessories and isn't called a "Tsunami in a Balloon", although when attached to a horseshoe it follows others.
- With all other Bottle variants (云, Fart, 沙尘暴, 暴雪) it is possible to jump a total of six times.
