This was used whenever an episode's name is shown in season 3 and 4 of LazyTown. I want to know what this font is so I can use it for a video I'm making.

esta fuente no esta a la venta , es una fuente hecha exclusivamente para LazyTown Entertainment

Found a similar font for you. This font is Neo Sans Star Ultra TR Regular.

Do not listen to LiLianJie! The real font is called 'LazyType Beta', made by LazyTown Entertainment in 2010 for the company's rebrand.
