Song
The Lemma song could be "Do the Owl" because they ball-room dance in it, and in another scene, there's an owl on Lachy's hand and Emma is behind Lachy flapping her arms like an owl. But it can also be "There Was a Princess" since Lachy plays the prince and Emma is the princess.

Video
The Lemma video is "Taking Off!" because they both make their first appearances in it, but can also be "Wigglehouse" since it features the prince-princess relationship of them.

Color
The Lemma color could be either Yellow or Purple because it's their favorite colors.

Animal
The Lemma animal is a Goat because they Emma loves goats and Lachy was dressed up as a goat in "Apples and Bananas".

Episode
The Lemma episode could be "Emma's Missing Bow" because Lachy helps Emma look for her bow, but can also be "Is That Lachy?" since Emma gives an alarm clock to Lachy in the Who Am I? segment.

Series
The Lemma series is Series 7 because they both make debuts.

Wiggle Friend
The Lemma friend is Captain Feathersword because Lachy played Captain in most of the Dorothy the Dinosaur shows so since Emma played Fairy Larissa in the shows Lachy played Captain, Lemma was Cemma for that moment.

Concert
The Lemma concert is the "Taking Off! Tour" since it was their first actual tour as Wiggles, and they played the prince and princess in "There Was a Princess" during one of the shows.

Theories
There was a swarm of Lemma shippers commenting on Emma's Christmas Bow on YouTube talking about the different theories of Lemma. These comments were removed by the creator saying "Sorry Lemma fans, Just didn't want to be shipping anything that wasn't 100% true!"
 * 1) Emma and Lachy are related somehow judging by their similar facial features
 * 2) Emma and Lachy are dating judging the fact their both young and always look at each other lovingly
 * 3) Emma and Lachys friendship goes back before their Wiggle days.
 * 4) Some fans support this by stating that they "look cute together" and some Twitter users have been asking questions like "Are you dating?", even though it has been proven that Emma and Lachy are really good friends (which is why Lachy and Emma haven't been replying to people who have been asking if they're dating)
