Where I can see SpongeBob in Spanish?

I'm learning Spanish in school, and I'm taking it very seriously, and I thought that because I know Sponge Bob very much every episode off by heart, I can see in Spanish and might be able to pick up a little more vocabulary. Youtube is not being very helpful for does anyone know where I can watch for free online or something?

Ever tried lookin 'for SpongeBob to On-Demand? Surely you have you On Demand. Who lives in a pineapple under the sea?
