Pulltoy patterns

As holidays approach I look for plans and patterns for pull toys I can
make on the scrollsaw. In particular I want to make those pulls toys
such as little cars, trolleys, buses, which have little passengers that
bob up and down as the toy is pulled. I have seen several at various
shows, but can't locate any source for plans. The books I have seen
don't seem to have these type of "active" toys. Appreciate any
guidance.
