Cowabunga dude! The Duggars decided to go the extra mile while celebrating Jennifer‘s 11th birthday on Aug. 2, by creating an epic homemade water slide for the special occasion. Michelle Duggar was even hosing the kids as they went down the hill and they all were having a blast while gathered for the huge bash. Watch the video above to check it out!

“Happy Birthday Jennifer! We love you sweetie and can’t believe you are already 11 years old! We have had so much fun celebrating with family, friends, and a homemade water slide,” the Duggars wrote on their Facebook page. Of course, fans were getting a kick out of the hilarious photo! “I sure hope they didn’t go down that slide with their skirts on,” one wrote, while another addressed how they were feeling major nostalgia. “The classic Duggar family homemade water slide! That was the part I loved the most watching you guys as a child!”

“We used to do this with same type of tarp! Such great fun! One tip — pour soap down the slide!” a third fan chimed in. Aside from the homemade water slide, the family also had a castle-themed Jolly Jumper and a huge backyard for the kids to play in, so needless to say, everyone was living it up to the fullest! Only a few of the Duggars were in attendance, but with all of the newlyweds and parents, it’s probably difficult to get the squad assembled.

Jim Bob Duggar, Michelle, and Jennifer posed for an adorable snap, and fans couldn’t believe how grown up their daughter is already! Jessa Duggar, Jana Duggar, and Anna Duggar were also there, smiling in a big group photo. When one person asked why Jill Duggar wasn’t present, one fan defended her by commenting: “Looks like a lot of the family isn’t in this photo! Why single out Jill?” Either way, it looked like Jennifer enjoyed her birthday party!
