According to the search results, the original Blippi actor is still involved in the show. Stevin John created the character and has portrayed him since 2014 on YouTube and TV. However, in May 2021, a new actor named Clayton Grimm was added to the show to occasionally take Johns place. Grimm had previously played Blippi in a live theatrical production of the show in 2019. The decision to add a new actor caused some backlash from fans who were caught off-guard by the change and criticized John for a "bait and switch" move. However, John continues to appear in a lot of Blippi content and seems to be working on Blippi behind the scenes as well.
