Underneath the background, you can choose where the bubbles will appear and at what frequency (each number is multiplied by ten to get the percentage, so 3 is 30%). Use the arrows to cycle through backgrounds. The Background Artwork box shows you the current background you want to use for the level. The denominator will adjust depending on how much every percentage totals up. Use the arrows to cycle through the objects, and click the numerator of the fraction to change the chance. The Bubble Costumes box allows you to decide what the chance will be of a bubble appearing in a stage.
One nice thing is that you can actually save levels in this game as the feature was not removed from the final product. It's actually a rather complicated level editor, so instructions are needed in this case. To access it, type ' room 13' in ScummVM's debugger. Much like other Junior Arcades, this one includes an in-house level editor the developers used. Into hegames.ini or scummvm.ini, or use ScummVM's UI. Par the course of Humongous games, this one has normally inaccessible subtitles.
