Überraschung! Endlich kannst Du von überall Deinen Freunden einen lieben Gruß schicken! Toll, oder? Und das nicht irgendwie, sondern hypermodern und trotzdem von Herzen kommend! Denn mit Saschas Gute-Laune-Grußkarten kannst Du kreativ sein und aus vielen verschiedenen Sprüchen, Motiven und Hintergründen der kunterbunten Grammel-Welt Deine ganz persönliche Grußkarte zusammenbasteln. Na, wenn das nicht mal ein Knaller ist! Platz für ein paar hübsche Grußworte gibt’s natürlich auch. Und dazu - ja was denn noch? Hört das denn nie auf? - kannst Du Deine erstellte GramMail sogar auf Facebook posten. Genial! Versuch das mal mit einer Brieftaube! Oder besser nicht. Ein grooooßes Dankeschön geht an die Jungs und Mädels der Firma Netzbewegung, die diese wundervolle App genau so umgesetzt haben, wie ich es mir gewünscht habe! Ich kenne wirklich wenige Firmen, die so kompetent, kreativ und freundlich agieren und dabei so menschlich bleiben. Ich verneige mich vor euch und eurer Leistung! Chapeau!

Austin's home is threatened. Help him clean up the Wadden Sea of garbage. Austin is an oystercatcher and his home is the North Sea, in the middle of the beautiful UNESCO World Heritage Wadden Sea. Every year a lot of garbage is thrown into the sea and into the beaches. But what can you do? To ensure that the North Sea and the Wadden Sea will be litter-free, Austin need your help! Your task is to clean the Wadden Sea by playing the games “Litter Fisher” and “Beach Collector”. He will count on you! In the Litter Fisher game, you have to tap the screen to move the net to collect the litter before the cod eats it. You can advance to different levels while playing. The aim is to unlock additional animals, such as a seal or porpoise. In the Beach Collector game, your aim is to remove the washed-up litter from the beach. To do this, you have to tap on the litter items as quickly as possible, before the next wave arrives and washes the litter back into the sea. Here to, you can play your way up to different levels. As a result, additional beach areas will be unlocked for cleaning. The more you play, the more litter disappears. Additionally, you will unlock success bonuses which you can access at any time. These success bonuses hide impressive pictures or “De Nümigs craft sheets” as well as other exciting information that you can share with your family and friends. For more information, please feel free to click on Austin at any time. He is sitting in the lower right-hand corner nibbling on some lugworms. The app is free to download and completely free to play. This game can include the following things: - Direct links to websites of the WWF Junior Programm, Junior Ranger of the Wadden Sea National Park, Visit Wadden, Wadden-Agenda Project and the websites of the Wadden Agenda project partners. - Pictures and PDF`s for free download and direct partial function via mobile phone.
