Umbrellas allow you to automatically advance a certain number of stages. Don't be in such a hurry to grab them, however. You might miss something important in a stage you skip. Each Umbrella is worth 200 points.
Crosses create alternate means of killing enemies, which create high point bonuses when defeated. The conditions to make crosses appear vary with the level of difficulty. Each Cross is worth 3000 points.

When you collect a staff or treasure chest in a stage, a large item will fall down the middle of the screen when the last enemy is defeated. All remaining bubbles on the screen will turn into small versions of that item, worth 700 points if collected. Staffs are worth 500 points, and will give you a large food item. Treasure chests are worth 1000 points, and will give you a large diamond.
When you collect a potion, all monsters are immediately removed from the screen and a number of items fill up the empty space on the screen. You are given 30 seconds to collect as many of these items as you can for bonus points. If you succeed at collecting all of the items, you will receive 100,000 bonus points. If you're playing a two player game, the player who collects the most items is awarded 100,000 points and the other player gets 50,000 points. If they collect an equal amount out of whole items on the screen (e.g. 30 to 30 out of 60), they can each get 100,000 points. The item that appears is determined by the color of the potion, but all the items are worth 500 points.
