As of 2019-05-15, I've added the proper boosters spritesheet, including the pastry bag animation. As you can see below, there's a suggestion of use, but you're free to use in any way you want to, obviously. (:

(Forgive my hideous finger. :'D)

Here are the other boosters animations. Note that I didn't do a GIF of the whisk because you can simply move it around the board to mimic a shuffling effect.

I've also added the winking face to all cupcakes and to the fruits as well.

Regarding the board elements, I've added a gift box (opaque) with unfolding animation; a glass/ice (transparent) with breaking animation; vanishing animations to the existing jelly, wafer and chocolate.

Finally, I've added the number count white bubble to the boosters icons.
