Copy NabiJr apps to Nabi2s

I have a NabiJr and a Nabi2s. My kids fight over the NabiJr because of the Nick apps on it. I have copied the apks over to the Nabi2s and they install fine, but some of them don't install icons on the home screen unless the app exists in the Google Play market. Since they don't install icons on the home screen they also won't install in the Nabi Apps, meaning they are not available except when in Parent Mode. The Dora/Team Umizoomi apps in particular are the ones trying to get to work. I have tried editing the apks, but I don't know much about that and haven't found out something that jumped out at me.

Thanks,
