Trick or Treat Studios

Trick or Treat Studios is a company that creates Halloween costumes, usually based on popular horror properties. They started releasing Goosebumps themed masks.

The company's first Goosebumps masks were based on Slappy the Dummy and The Haunted Mask, and these were released in late 2017. They also released a life-size Slappy ventriloquist dummy replica based on his appearance in the TV series around the same time. In late 2018, they're releasing masks based on the TV version of The Pumpkin Heads and The Haunted Mask. However, in June 2018, Trick or Treat Studios announced that they would stop making Goosebumps masks by 2019.

In early 2022, Trick or Treat Studios got their licence back, it is unknown when they plan to rerelease the masks.

Licensing and discontinuation
The masks made by Trick or Treat Studios were officially licensed by Scholastic Media. In a Facebook post made on June 29, 2018, Trick or Treat Studios announced that 2018 would be the last year in which anyone could buy their Goosebumps themed masks because they would not be renewing their deal with Scholastic Media for the next year. In the comments to this post, Trick or Treat Studios revealed that Scholastic Media had forged a "direct to retail agreement only with Spirit Halloween."

Renewed License
In early 2022 the Goosebumps masks were listed in their 2022 catalog. As of right now, no new items have been added to their catalog, only featuring previously created masks and props.
