To help with this, I have created a level that can be used to earn the achievement.
If you pick up all of the score bubbles in one combo then the score will reach 1 million. If you have played other levels already then you probably won't need to collect them all.
If you search the community levels for me as an author, wilberforce072, you will see a level called TT trophy level.
It will also help you earn a number of other trophies.
Let me know if you have any trouble with it.
