The ToonTown spoofer is a program that allows you to use 2 or more ToonTown accounts on one system. It also has a few extra programs that really help a lot once you get the hang of them.

What the ToonTown spoofer contains:

'Joe Fish' automatic fisher
'Gardener Flora' automatic gardener
'NightLife' reanimated ToonTown graphics
A invasion timer
A racing timer and checklist

The ToonTown spoofer costs $30 (U.S.) for a key that works for activation on 3 computers.
It's very helpful when you have to do tasks and no one's around. You can also do two man CFOs, VPs, CEOs and CJs by using 2 accounts at once. It's very helpful for soloing the pie/crane/seltzer/evidence round.
I recommend buying it.
