Megg announced today on the Club Penguin blog that both Sled Racer and SoundStudio have been removed from the iOS and Android app stores. She said they were removed to help the team focus more on Project: Super Secret and the year ahead. If you already have the apps, you can still play them on your device, however.
Here is Megg's full blog post:
