"Lachy" is the purple Wiggle. He replaced Jeff and is younger than him but, like Jeff, loves to sleep. Like Greg and Sam, he is the lead singer in most of the songs. Some of the notable songs he sings lead on are Rock-A-Bye Your Bear, Let's Go! We're Driving In The Big Red Car and The Shimmie Shake. He plays the keyboards, just like Jeff, which makes him the only Wiggle to not have changed instruments with the new generation. He also plays the Tambourine, guitar, and accordion on occasion. He likes inventing, but most of his inventions backfire and don't go well.
