The birds are back, and they’ve got the Force on their side. Angry Birds Star Wars dresses the birds as Luke Skywalker, Obi-Wan Kenobi and other characters, and gives them extra powers to knock down those pigs, which are now Pigtroopers. Luke has an obstacle-slicing light saber, Obi-Wan has the Force, and Han Solo has a blaster. The game opens on the planet Tatooine, moves into space — where you have to deal with zero gravity — and then to the Death Star, which has the face of a pig. If you fail a level, a Darth Vader pig appears and laughs, or oinks, at you. A free bonus level features R2-D2 armed with a tractor beam and a C-3PO that falls apart. Gamemaker Rovio promises a free update featuring the snowy Hoth planet. Will the pigs strike back?
Rovio. Android: free; ad-free version for Android, iPod Touch, iPhone, iPad: 99 cents; HD version for iPad, Kindle and Nook: $2.99. In-app purchase of second bonus level: $1.99.
Where’s My Perry?
Perry the Platypus from Disney’s “Phineas and Ferb” has a spin-off of the popular “Where’s My Water?” app. Perry, or Agent P, needs to get to his underground base to uncover the latest schemes of evil Dr. Doofenshmirtz. But the water that fuels his transport tube has been blocked by gates and lasers that change water to steam or ice. Players have to find a path for the water and try to collect bonus gnomes along the way. The free version has one mission with a dozen levels. Paid versions include four missions with 20 levels each.
Disney. Android, iPod Touch, iPhone, iPad: free; ad-free version that includes more levels: 99 cents; Nook: $1.99.
Meet the Insects: Forest Edition
December isn’t prime time for nature walks. But if you love bugs, you don’t have to wait until spring to see butterflies, cicadas and stink bugs, thanks to this app. Check out a video of two male Japanese beetles fighting over a female or a brown cicada turning into an adult. You can read about insects’ life cycles, their colors and patterns and their habits. The app features no games, but there are two types of quizzes to test your knowledge. An observation journal for when the weather cooperates helps you investigate what insects are in your back yard or neighborhood park. You can even upload pictures to your virtual journal. Developer NC Soft, which worked on this app with the National Science Museum in South Korea, promises that more insects are on the way.
NC Soft. iPad only: $3.99.
If you’re particular about what you wear and enjoy mixing and matching clothes, Toca Tailor is a good fit for you. Four characters — a boy, a girl and two animals — come simply dressed in a shirt and pants. A slide of the finger turns the pants into shorts. A tap changes the style to puffy or cutoffs or a miniskirt. Tap on the box with the thread to change patterns — and you can pick more than one. (How about shorts that have polka dots on one leg and leopard spots on the other?) You can also add pockets, buttons and zippers to your colorful creations. Complete your outfit with hats, scarves, shoes and other items from an accessories box. When you’re done, click on the mountain symbol to take a picture of your model in whatever setting you choose. Photos will save to your device’s camera roll so you can e-mail them to friends.
