Why can't I buy the 2nd episode?

I purchased an iPad Air in January 2014 and I downloaded the legends of Ooo app. I really love the app and so do my kids. I wish I could find another app just like this one. I tried purchasing the 2nd episode but it won't let me. I click yes to buy and then it takes me to a story line screen about LSP and then it just sits there. It won't do anything else. I even tried purchasing the 2nd episode on my daughter's iPad Air, my son's iPad mini, and my iPhone 4s and it still wouldn't let me buy it. I even tried to purchase it again tonight after I updated our apple software to the new 7.1 and it still didn't make a difference. Please fix this app!!! We have been waiting for 2 months to buy the 2nd episode.


No matter what device or generation of their phone/iPod/iPad many people can't seem to give Marcy the toilet wand. So I found that to give it to her you must place it on her head. This needs to be fixed and fast though because you should be able to place it anywhere on her body. Also, whenever I try to buy the next episode of the game it freezes up. I'm still trying to find how to fix this but according to many other adventure time lovers that I know, you need to beat both versions of the first episode, close out all of your screens, click BMO (it'll say you need to beat the level) and then you try to buy it. You need to have connection the entire time. This didn't work for me but it might for others.

Great Fun game!

First of all, the voices, the actual voice actors! Super cool, thanks. Secondly, the music in the new BMo Noir is amazing! I let it play for a real long time and just felt like I was at an experimental jazz nightclub, smokey! And of course, BMo dialogue is supremely entertaining. And lastly, Pendelton himself has graces us with an LSP version and it was hilarious! I'm so grateful that these people work so hard on their cartoon because it really makes me SO happy! Thank you allowing me to also have BMo in my pocket. It makes me happy on the subway!
