Streamers and balloons just won't cut it these days at kids' birthday parties. Luckily, parents can leave it to the experts to transform their backyard into a birthday wonderland. From inflatables to wild animals, many companies offer birthday rentals to provide your child with a memorable birthday experience.

Check out some of the top picks for birthday rentals in the Atlanta area.

Human Hamster Balls. Prices vary, generally $165 per hour, $65 each additional hour. Le Balls. Multi-hour discounts available. 678-371-9090. www.bandaamusement.com.

Get the kids rolling — inside giant inflatable balls that is. When you rent these Human Hamster Balls, attendants will do all the work inflating each ball, helping kids get inside safely and initiating play so the children know what to do. Kids at least 7 years old and 4 feet tall can take part. You need to provide only a power source and an area to roll around in.

Rock Climbing Wall. Prices starting at $750 for two hours. Action Packed Parties. 770-466-3437. www.actionpackedparties.com

Little did you know you could rent a 24-foot-high rock climbing wall for a birthday party. The experts at Action Packed Parties offer a rock climbing adventure with four climbing stations, so up to four children can climb at once. For additional excitement, add the bungee trampoline, which allows partygoers between 20 and 200 pounds to fly into the air in a safe way. Just make sure before you rent that you have enough clearance for the set up of these structures.

Safari Gator Challenge. $399 for six hours. Astro Jump Atlanta. 770-529-0053. www.astrojump.com.

Not all inflatables measure up, but the Safari Gator Challenge certainly does. This one-stop inflatable shop will cover all of your bouncy house needs. Not only will your children enjoy bouncing around in this 54-foot-long structure, but they'll also have a blast with all the ladders, slides and 25 hidden obstacles inside.

Velcro Wall. $260 for eight hours. Jumptastic. 404-537-1805. www.jumptastic.com.

Kids will find themselves in a sticky situation when you rent the Velcro wall from Jumptastic. Once children get suited up in the special Velcro suits (they provide two,) they'll run down an inflatable castle and jump against a Velcro wall to stick to it. You might need to rent the Velcro Wall for kids ages 5 and up so that they can run, jump and stick themselves to the wall without much assistance.

Animal Encounters. Prices starting at $200 for a 45-minute program. Wildlife Wonders Zoo to You. 706 348-7279. www.wildlifewonders.org.

Bring the wild animals right to the party with the Animals Encounters offered from Wildlife Wonders Zoo to You. A typical program lasts about 45 minutes and includes animal presentations; a handler who can talk about the creatures and answer questions; safari or cowboy hats for each guest; bookmarks, temporary tattoos and coloring sheets. Choose from a wide variety of packages, including the Safari Party Rainforest Adventure, Out of Africa, Australian Outback, Asian Extreme, Bugs and Friends, and more.
