According to the test release notes, in Beta 1, there was a game called Dodge-A-Cog, where you had to collect the candy, but stay away from the cogs. If you got all the candy in the level, you got a bonus. (This may have possibly been an old version of the Catching Game.)
You had to take pictures of toons in the playground you're in. You'd get a bonus if you take a picture with good quality. You'd play until you ran out of film. This game was removed, because it caused a crash on Mac computers.
Trolley Tracks was a special trolley game that occurred every Thursday and Silly Saturday. It was removed on May 24, 2012.
Every Toon in Toontown came out to see the ribbon cutting when the first Jolly Trolley came to Toontown Central. Unfortunately, it was Goofy who laid out the trolley tracks, so you never know quite where you'll wind up! Of course, you never need to "wind up" a Jolly Trolley - Invented by Gyro Gearloose, they run on laugh power, so they'll ride the rails as long as Toons keep laughing - which should be a long, long time!
Toons used to stand on the trolley, but they now sit.
