Slippery Bridge

Zack and Rex try to cross a mud pit on a log. But the log is wet from the rain and is too slippery for them to get across without falling in the mud. They try going slow, but that doesn't work. Rex tries dropping sand on the log, but the sand he drops when he drives forward doesn't get under his wheels and he falls off. When he tries dropping the sand by going backwards, he can't see where he's going and ends up in the mud again. When they go off looking for answers, Zack discovers that a second log placed against the first keeps them from falling off, no matter how slippery both logs are. With Strut's help they place a log alongside the first and it keeps them from sliding sideways.
