Here is the group shot from HappyMeal.com:
As best I can tell, the "boys" will get Giants while girls will get Fijits Shimmies. So, if your daughter wants that new Jet-Vac, make sure to denote you want a "boys" Happy Meal.
That said, your other option...should you not have kids, grandkids, nieces, or nephews and don't much care for the food...you can usually walk in and purchase the set.
I went out with my family Friday night and we got 4 Happy Meals. The end result? 3 Drobots and 1 Crusher. Not exactly what we had hoped for...That made me realize how important it would be to land the set by just purchasing it. That McDonald's refused to sell me any (ie employee doesn't know, doesn't care, or doesn't want to do it).
I got pretty lucky Saturday and found a store willing to sell me the set (or in my case, all but Drobot). They brought out 2 new boxes (one was white and blue, the other white and black). It took a few minutes for 2 employees to find all 8...I noticed Kaos and Chop Chop were the last two to be fished out. Meanwhile, they accumulated a stack of Drobots and Tree-Rexs on the counter.
As soon as I heard the price was $1.69 per toy, I knew I made the right call. With tax, I walked out the door with all 8 that I needed for around $14. When we got 4 Happy Meals Friday night, we were out $15 or $16. Plus, I had some bad nuggets, lol. That said, this worked out quite well as I now don't have to buy more Happy Meals, beg to exchange duplicates, or worry that between kids, collectors, and scalpers I might miss out on Kaos (the one I really wanted the most).
Here are a few videos highlighting the complete set and individual openings for more detail:

1. Tree Rex
3. Gill Grunt
7. Chop Chop
Note that I ordered them by their toy number which you can find on the bag (1-9). You might also find this interesting:
All 8 Elements are covered with 1 Skylander. Kaos makes up the 9th.
Series 2 Skylanders: 5 (Spyro, Gill Grunt, Drobot, Chop Chop, Ignitor)
Newlanders: 1 (Jet-Vac)
Giants: 2 (Tree Rex and Crusher)
Light-up Effect: 1 (Tree Rex)
Projectile Effect: 3 (Spyro, Gill Grunt, Jet-Vac)
Inertial Move: 1 (Crusher)
90 Degree Move: 2 (Chop Chop, Ignitor)
Wing Flap: 1 (Drobot)
Face Switch: 1 (Kaos)
Projectile Strength (Farthest to Shortest): Spyro, Gill Grunt, Jet-Vac
The best news is that the toys all look much better than you would think based on the online appearance at happymeal.com.
They lack the secondary colors and detail you are used to with regular Skylanders, but for $1.69 they are pretty nice.
Overall, this is a nice, affordable set for collectors and something kids will really enjoy and look forward to...
The real draw for me still remains KAOS. He is a nice size and I am fine with the limited action due to just finally having a Kaos figure to include with the rest of the collection...I think he will easily be the most sought after....
Good luck landing your favorites, or completing a set!
