You clearly didn't play all of the levels, picking up rubbish was just the start

Spain, officially the Kingdom of Spain (Spanish: Reino de España, unofficially in Galician: Reino de España; Catalan: Regne d'Espanya; Basque: Espainiako Erresuma; Occitan: Regne d'Espanha), is the largest of the three sovereign nations that make up the Iberian Peninsula—the others are Portugal and Andorra—located in Southern Europe. To the west and to the south of Galicia, Spain borders Portugal. To the south, it borders Gibraltar and, through its cities in North Africa (Ceuta and Melilla), Morocco. To the northeast, along the Pyrenees mountain range, it borders France and the tiny principality of Andorra. It also includes the Balearic Islands in the Mediterranean Sea, the Canary Islands in the Atlantic Ocean and a number of uninhabited islands on the Mediterranean side of the strait of Gibraltar, known as Plazas de soberanía, such as the Chafarine islands, the isle of Alborán, the "rocks" (peñones) of Vélez and Alhucemas, and the tiny Isla Perejil (disputed). In the northeast along the Pyrenees, a small exclave town called Llívia in Catalonia is surrounded by French territory.
