Christmas came early this year for ThunderCats fans!

As of Thursday, the beloved animated series and the 2011 reboot are available to stream on Hulu — and fans are freaking out.

Hulu confirmed the news on Wednesday, tweeting "ThunderCats HO!" alongside a fan announcement.

"@Hulu just won BIG time with the Thundercats!!!!" one fan tweeted.

"80s babies. Thundercats is on Hulu! This is not a drill!!!!" another fan said.

"Cannot believe how long it's taken to get #ThunderCats on a streaming platform. May be the best news of 2020," tweeted another.

"I need every freaking HULU subscriber to watch 2011 ThunderCats..." said another fan. "I'm begging for a Season 2. I'll never understand why Cartoon Network dropped the ball on this. Hopefully having a bigger audience will give it the Avatar affect."

"Thundercats is now streaming on Hulu. Both the original 1985 series, and the 2011 reboot are online. I grew up on the original Thundercats, so it's a nice little trip down memory lane AND, it's plenty to watch while socially distancing!" added another excited viewer.
