Do-Do #3

In "Big Top," Do-Do and his circus troupe arrive in the eccentric town of Ruffville, where their performances initially fall flat with the skeptical audience. When the crowd turns rowdy and threatens to mob Miss Dolly after her act, Do-Do devises a clever plan using inflated circus balloons to scare them off—revealing the "giants" are just oversized party decorations.

Do-Do returns to his old college, Wagtail University, where Dean Barker convinces him to run in a cross-country race against rival Catskill College—despite having no experience. As Do-Do competes, he faces sabotage from his old rival Hotspot and a tricky challenge from Slim, who tries to trip him at the finish line.

A young woman and her dog mysteriously find themselves transported to Valley Forge during the Revolutionary War, where they join a circus troupe pretending to be soldiers. When they discover the American troops are starving, the group devises a daring plan to sneak food and supplies past British lines using a circus wagon disguised as a Trojan horse.
