One of the related YouTube videos to Spook House Dave’s channel led to ‘Transylvania TV’ (or TVTV), a puppet show from Minneapolis. More adult themed in nature (language, content, nothing too graphic) it’s not for kids despite being very similar to your Sesame Street/Muppet fare.
They have a DVD of their first season out (as well as t-shirts, which run rather cheap for some designs) but you can view the whole season for free on their You Tube account. Season Two is on their site, though it’s a continual process. Subscribe to their newsletter to stay in touch.
