The live-action show will premiere with back-to-back episodes on Monday, August 24, at noon ET/PT, followed by two weeks of new episodes Tuesday, August 25—Thursday, August 27, and Monday, August 31—Thursday, September 3, at noon ET/PT. You can already watch some videos at the Nick Jr. site, in the remote chance that your child isn't seeing enough promos on your actual TV. (Though they don't currently have "Stuck On You," a song which is almost tolerable for repeated adult listening. By "repeated," I mean twice. I have limits.)
Don't say I didn't warn you. Please plan accordingly.
