Level 502 is the 12th level in The Tranquil Oasis and the 122nd animals level in Bubble Witch 2 Saga. To pass this level, you must save 6 animals and score at least 4,000 points in 18 moves or fewer. When you complete the level, Bubble Rain is activated and will score you additional points.
- This level is very hard. Six animals in only 18 moves seems hard, but there are some Bubble Mills. However the last animal is almost impossible to get.
- Aim high and drop large groups of bubbles. Don't waste moves on Bubble Mills but take them when there is an opportunity. Eliminate Bat Bubbles whenever possible.
- The last animal hangs on two cloud bubbles. It needs some luck for a match here. Clear both sides.
