can anyone tell me what nick toons is? is it toon disney?

its Nickelodeons Cartoons

can you tell me like what cartoons would be on it?

Any Nickelodeon-made cartoons - Rugrats, Angry Beavers, Fairly Oddparents, Spongebob Squarepants, etc. If it was made/produced by Nickelodeon, it's on there.

The key words are "made/produced". Lots of cartoons have been shown on Nickelodeon that aren't their own, like Mysterious Cities Of Gold, Belle and Sebastian, etc.
