Lachy (or Lachlan) is the Purple Wiggle who replaced Jeff in 2013.
Like Greg and Sam, he is the lead singer in most songs. Some of the notable songs he sings lead on are Rock-A-Bye Your Bear, Let's Go (We're Riding In The Big Red Car) and The Shimmie Shake!. Since early 2017 he has taken over the role of main lead vocalist for the group, whereas he previously shared this with Simon a little more evenly.
He plays the keyboard, just like Jeff, which makes him the only Wiggle in the new generation to play the same instrument as his same-coloured predecessor. He also plays the tambourine, guitar, drums and accordion on occasion.
He likes inventing, but most of his inventions backfire on him or have an accidental side effect.
- He is the current youngest male Wiggle.
- He likes playing all types of pianos and keyboards.
- He likes sleeping, just as the previous purple Wiggle Jeff did.
- One of his most known features is his curly hair.
- He narrates the book Stories On The Move A Wiggly Dance.
