similar to the FP garage, but makes noise (super! thanks, Michele and Alan!).
Unfortunately the ramps do not screw in so that the boys were able to detach them at will. Tonight I have used two tubes of Super Glue in an effort to secure the structure. I waited until 11, though, and found it particularly annoying that there is no "off" switch so that Cookie Monster kept yelling "Out of the way! heh.heh.heh."
Thank you, that's very helpful.
