HOW DO THE TTTE CAST LAUGH?
Thomas - a rapid fire laugh that's incredibly infectious. Kind of your standard HAHAHAs or HEHEHAHAHs but it's still very genuine and liable to make others laugh as well
Edward - he wants you to believe that his polite little "hmm-hmm-hmm"s are his laughs. His actual laugh is a squawky, ugly, incredibly loud seagull laugh that only Thomas knows about.
Henry - a wheezy laugh, kinda sounds like "eeeh-heeeh-heeeh". Not a loud chortler but completely unable to articulate words.
Gordon - a deep, rumbling laugh. AHO-HO-HOs. Embarrased over his own laughs so he immediately composes himself and goes ENOUGH
James - a squeaky, chipmunky laugh like EHEHEHEHEEEH. He snorts a little, too. Tries to make it sound more impressive, like NYEHEHEHEH! but if it's funny enough he devolves into his true laugh sooner or later
Percy - a cutesy little heeheehee laugh but it oscillates between that and a racouous AUGHAHAHAHA laugh
Toby - dad chuckles- not exactly laughs, it's not too loud for them. Slaps his knees as he chuckles. Like ohohohohoho!
Duck - a snorting, honking, slurpy and damp mess. It definitely sounds like a duck quacks. Like its like eheheh-*SNRK*-heh-*SNRK*-heh-*SNRRK*-
Donald - deep, throaty HAGH-HAGH-HAGH-HAGHS while also elbow nudging the guy who made the joke appreciatively
Douglas - The same HAGH-HAGH-HAGH laugh as Donald, but completely different reaction; he immediately beats the nearest object up in the vicinity. Slamming tables, punching walls. If he's just an engine he just shakes helplessly as he laughs.
Oliver - His laugh used to be loud and genuine, a real YEHAHAHAHGAHAHAHAH with tears in his eyes kinda laugh but he learned to be quiet during the escape and never quite unlearned it when it comes to laughs. It's now kinda like, quiet chortling.
Emily - a regal, queenly laugh of O-HO-HO-HO! but when she breaks down it devolves into banshee like shrieks
Nia - it sounds like tsshAHAHAHA! tssshAHAHAHA! Like she tries to hide her real laugh at first but cant help it, and it sounds so clear and genuine
Rebecca - laughs a lot, so everyone's used to her giggling, but it's always a welcome sound! It's a cute little, high pitched and rapid fire hee-hee-hee! And she sounds so delighted every time. When she laughs louder its like HEEAHAHEEHAHA!!!!
