40 moves to match 12 vampire snails, and there are a bunch of obstacles in between. Begin by getting rid of the six vampire snails that are not in any Gift Traps. Sticky Cobwebs will randomly trap snails and special gifts specifically, so keep that in mind and don’t waste turns without a good reason. The sooner you reach the left grid, the sooner you can start releasing the snails from their traps. Because of their erratic movement, and the constant Sticky Cobwebs hindering your progress, it might be better to release one snail at a time, if at all possible. Otherwise, a lot of special gifts ought to do the trick.
You can also consciously chase down specific snail colors. If there are four blue snails for example, and some of them are trapped, and there are a couple of other snails, one or two of the same color, it might be better to focus on these lesser numbers. That way, you can use the color gift that is in the middle of the grid, to explode the remaining blue gifts and blue snails, all at the same time.
