Drag Scratchy, Alonzo, and Gobo. Click charmander83 to make him bounce. Click the icon in the bottom right to show the help screen. Click the help screen to hide it.
This is a custom block I made. Alonzo is from snap https://snap.berkeley.edu/ The help screen is a modified version of the help screen of if on edge, bounce. Snap version: https://snap.berkeley.edu/project?user=charmander83&project=If%20on%20sprite%2C%20bounce
