Bubble : Cascade

Bubble : Cascade is the reason Bubble matters in the rolling economy: the base aura was a shop purchase, but this mutation was rollable in the Summer 2026 event. The wiki gives 1 in 110,000,000 in Blazing Sun and 1 in 55,000,000 in Incinerator, which at 10x luck is about 11 million and 5.5 million rolls. It was added in Eon 1-26.5 and became unobtainable on 27 September 2026.

Visually the player floats in a relaxed pose with water swirling around, four big bubbles hovering nearby and smaller ones rising and popping. A tiny bubble duck circles the player and sometimes stands still instead of spinning. The wiki also records that its theme was changed on an unknown date while the collection still plays the old one, that it can walk on water, and that it is the most common Summer 2026 global.
