Slash voices himself as the third judge of the Battle of the Bands competition in Battle of the Bands.
- Slash is the first person to guest star as their own self on Milo Murphy's Law.
- Slash also appeared and played Kick it up a Notch, a song from Phineas and Ferb, the previous show created by Dan and Swampy. He got "animated" and played together with Phineas and Ferb, this song is seen and heard at the end of Phineas and Ferb the Movie: Across the Second Dimension, and it was also the promo for the movie. The fact that he appears in Milo Murphy's Law, which is set after Phineas and Ferb may be a joke on how he's been in "animation mode" inside the tri-state area all this time.
