Thomas & Friends: Splish, Splash, Splosh! (2010)

Even when it's wet outside you can still have plenty of fun, especially when you share your adventures with Thomas and his friends! Grab your galoshes (wellies in the UK release, gumboots in the Australian release) and join the team as they prepare for rainy day visits and soapy spills, and then get unstuck from a snowy situation in this collection of stories from the Island of Sodor.

Unfortunately the movie Thomas & Friends: Splish, Splash, Splosh! is not yet available on HBO Max.
