After the stint with Channel 101, Justin was offered to create animated sketches for VH1s program Acceptable TV (2007). During the artist’s time in his new show, he created and voiced a fan-favorite character named Mr.Sprinkles.
Through this character, he explored some mature and controversial topics such as homegrown terrorism and racism in an adult fashion yet again. But most of the sketches he created for the show didn’t end up being telecast due to a content publishing limit from the network.

Post Acceptable TV, he then worked on shows such as 2 Girls, 1 Cup (2008), The Sarah Silverman Program: Animated Webisodes (2007). However, his voice acting career only took off when he was approached by Disney to star in its cartoon named Fish Hook (2010-2014).
Although the content on the show was drastically different from the adult humor Roiland was used to performing, he gave it a shot to learn the craft of the animation. During an interview with Vanity Fair in 2020, he shared:
"They pitched me this fishhooks thing and Alex was looking for someone to develop it.And it was very different.I was like oh, I haven't done this before, I could learn stuffs and this could be very fun just to see how Disney makes a show here so and how can I rise to that challenge and try to help make something that can be good."
During his time at Fish Hooks, another mainstream project from Disney’s followed called Gravity Falls(2012), in which he voiced a titular time-traveling character named Blendin Blandin.

And from 2011 to 2018, Roiland was also involved in another popular show titled Adventure Time (2011-2018) as a voice cast of a weird character named Earl Of Lemongrab.
