"Really? The readers won't laugh at a steam engine blowing bubbles?"
"No, no, you look beautiful. It's a work of art.”
―Snap and Olwin

Bubbly Olwin is the forty-eighth episode of the first season.


Olwin has a Chug Wash and is delighted to hear that a Welsh-Scottish photographer is coming to Chuggington to take pictures of steam engines. While passing by the main depot area, she encounters Puffer Pete on his way to the quarry, where she reluctantly lets him go despite her fears that his bodywork will get roughed up. She spots Brewster and Wilson fighting over a wagon filled with 100 bottles of elephant soap wash in the loading yard on her way back. They both want to take the soap to the safari park and observe Ebo get washed, much to Wilson's dismay of not wanting to take a boxcar to the 'boring' farm.

In a struggle, Wilson's coupler lets go of the carriage, and the wagon jolts upwards, shooting a bottle of soap into the air, which gets sucked down Olwin's water tank intake valve. Olwin, at first, doesn't know what just happened and dismisses it as she thinks her nerves are getting to her head. To resolve the situation, Olwin volunteers to take the boxcar to the farm to allow Wilson and Brewster to go to the safari park.

At the farm, the bottle of soap ruptures in Olwin's tank, and she feels its strange effects. Harrison then stops by, wondering why he rarely sees Olwin at the farm, despite knowing that she should make herself 'even more beautiful'. Olwin complements his statement but smells Harrison's cargo fumes - cow manure laced with fertilizer in a hopper car. Olwin tries to get Harrison to depart faster. In an attempt to sabotage her photo opportunity, Harrison deliberately jolts his car to cause some manure to spill out and land on the track. Koko then appears and speeds down towards the spillage, and despite Olwin's warning, Koko doesn't hear it and inadvertently splashes the gunk near Olwin's mouth!

Horribly embarrassed and disgusted, Olwin becomes paranoid of being noticed and gets Vee to be on the lookout, so that Olwin can reach the Chug Wash urgently and unnoticed. But her ordeal complicated, when Olwin finds out that the Chug Wash is broken and Eddie rudely couldn't care less. Olwin tries to go to the repair shed for Lori to clean her up, but Morgan is fixing Irving and tells her that Lori is at college.

Determined to get fixed, Olwin tries to use the water refueling yard to wash off and top up her tank, which causes the soap inside the tank to sud up and produce huge amounts of bubbles. The bubbles come out of every piston and chimney, much to Harrison's humor. Determined to find out what's happening, Olwin returns to the repair shed to get scanned, and Morgan confirms it to be the elephant wash bottle. By now, the photographer has arrived and is photographing Pete and Zephie. Olwin hurriedly heads to the safari park in a last effort to get washed, and Ebo thankfully volunteers.

The photographer arrives at the safari park, just in time that Olwin is completely cleaned. The photographer is amazed by a bubbling steam engine, which uplifts Olwin, and they snap a photo to feature on the front cover of Chuggington's newspaper.
