Jiminy Cricket can be okay for this, especially since his star appears in the same spot, but while his star might help you create the items, the trick is going to be getting them all down unless you can combo another star with a power-up later on.
There are a couple tricks that I use to help with these missions:
(1) The first I like to call "bring the star to the item". So if you're using an emoji like Jiminy where the star is going to be in a fixed place, if you can "catch" an item at the bottom by making sure there's a cloud or sun powerup
under it, you can then work on bringing the star down to the item to combo it.
(2) A slightly easier trick to execute is "bring the item to the star". Get the star down to the bottom of the board. Work on only clearing the column above the star, to the left of the star, and to the right of the star as much as possible, until an item drops within one column of the star. If it drops in the same column as the star, then you just have to lower the item, but if it drops in the column adjacent, you want to get the item about halfway down or lower. Then, using a cloud or sun powerup, force the item down to the bottom. If you're quick with the timing, there's a brief lull between when the item falls off the bottom where you can combo the star with the item, but...
not if the item was too far up when you did this. It also doesn't seem to work if you make a match below the item that calls it to go to the bottom.
As far as which emojis might be best, some possible choices (I don't know who you have) are:
- Emojis that create their own stars. Jiminy does this, but he's a little slow, especially at lower levels, but if it's who you've got, it's who you've got. I don't know where you're at with Tinkerbell, but she might very well do the trick if you've gotten her from the recent Peter Pan event (her stars can be somewhat unreliable, but when they go... oh, man).
- Duplicator emojis. I see you're relatively low level, so interestingly enough I like Randall and Flounder from the Silver Box for these types of missions until you've got better duplicators from the Gold and Series Boxes.
- Emojis that put items on the board. The only one you might have at this point is probably Gus from the recent Cinderella event, but Holiday Mickey will be an emoji you'll want when he comes back next month, and Chip (of the Rescue Rangers variety) is a good Gold Box substitute but hard to obtain with how full that box is.
If you want to run some of the other emojis you have by us, I'm sure we can help you figure out if there are better candidates to use. Otherwise, patience with Jiminy ought to get you there eventually.
