Teletubbies-Who's behind the costume?

actors and actresses of teletubbies
Tinky Winky (played by Dave Thompson, Mark Heenehan, and Simon Shelton) is the first Teletubby. He is the largest of the Teletubbies, is covered in purple terrycloth, and has a triangular antenna on his head. He is notable for the red luggage (described by the show as a "magic bag", but often described by other media as a handbag) he always carries. His character has caused controversy due to allegations that his character's behavior, bag and body colour have homosexual connotations (see below).
Dipsy (played by John Simmit) is the second Teletubby. He is green and is named "Dipsy" because his horn resembles a dipstick. He likes his black and white furry top hat, which he once lost and later found. He is the most stubborn of the Teletubbies, and will sometimes refuse to go along with the other Teletubbies' group opinion. His face is also notably darker than the rest of the Teletubbies, and the creators have stated that he is Black.[7]
Laa-Laa (played by Nikki Smedley) is the third Teletubby. She is yellow, and has a curly antenna. She likes to sing and dance, and is often seen to look out for the other Teletubbies. Her favourite thing is a bouncy, orange ball, which is almost as big as she is.
Po (played by Pui Fan Lee) is the fourth and last Teletubby. She is the smallest and youngest of the Teletubbies, is red, and has an antenna shaped like a stick used for blowing soap bubbles. Her favourite object is her scooter, which she calls "scoota" (she also calls it "Po 'cooter!", or just "cooter"). Po can sometimes be mischievous and naughty, as when she disobeys the commands of the "voice trumpets". She has been stated by the show's creators to be Cantonese[7], and as such, she is bilingual, speaking both English and Cantonese. Although many are unsure of Po's gender, or consider her to be male[citation needed], she is clearly referred to as female in several episodes, such as in the episode "Dad's Portrait". Many refer to her as "he" even though it is "she" (the same happens with Laa-Laa).
