The tracks "Zankyousanka", "Urgently Jammin" and "Forest Maze" (no '_') also have them. As a side note I found a neat trick to make finding them easier. If you're subscribed to a bunch of songs on steam you can search your workshop folder for the folder "CustomPortRifts" to see which have them.

The tracks "Sneaking Out" and "Ultimate Legend of the Untrained Demon King (Heavy Rock Mix) - Puyo Puyo Champions" both have custom sprites.
