Why does Thomas the train keep Changing Color in this fun toy train story? #thomasthetrain #thomasandfriends

Achoo! Achoo! Achoo! Achoo! Oh dear, what's happening? Why do I keep changing colour? Thomas? Thomas! I'm over here! Huh? Thomas? No, over here! Over where? Ah! Oh, there you are! Why are you a different colour? I don't know. Every time I sneeze, I change colour. Achoo! Come on Thomas, we need to start our work! Oi, Thomas! Where are you, Thomas? I want to work with you! Oh no, is that Diesel 10? He seems angry! Thomas? Thomas? What do we do? We need to hide! He's coming! Achoo! Phew, that was a close one! I sneezed just in time! I wonder what he wanted? And why was he so angry? Achoo! Oh, is that Percy? Maybe he'll know what I can do! Ah! That's not Percy! What's going on? Come on Thomas, we still need to start working! Oi, Thomas! Where are you, Thomas? I want to work with you! Oh no, is that Captain Funling? He seems angry! What do we do? We need to hide! Quick Thomas, sneeze again! Thomas? Thomas? Come on Thomas, he's coming! Achoo! Phew, that was a close one! I sneezed just in time! I wonder what he wanted? And why was he so angry? Achoo! Oh, is that Gordon? Maybe he'll know what I can do! Ah! That's not Gordon! What's going on? Come on Thomas, we still need to start working! Oi, Thomas! Where are you, Thomas? I want to work with you! Thomas? Thomas? Oh no, is that Iron Harry and Iron Bert? They seem angry! What do we do? We need to hide! Quick Thomas, sneeze again! Achoo! I can't, Funling! I think I'm all sneezed out! Oh dear! Um, I have an idea! This feather might make you sneeze! Come on Thomas, quickly! Come on! Oh, they didn't spot us anyway! Oh salam! Achoo! Huh? What was that? Was that you, Thomas? Uh oh! Oh, you're not going anywhere, Thomas! Ha ha ha! There you are, Thomas! I've been looking everywhere for you! Have you guys found Thomas? Oh dear, oh dear, oh dear! Thomas, I've been wanting to do this all day! Oh dear, oh dear, oh dear! Here you go! It's medicine for your sneezing! Oh, that's why everyone wanted me! Yeah, otherwise you couldn't work as well! We gave some to every engine! Like Percy! And Gordon! That's good! Thomas was the last engine, so now everyone can work without sneezing!
