Ronald being able to get past all of Franklin's tests is awesome in its own right. This especially applies to when he's able to answer the riddle, prompting Franklin to have a Villainous Breakdown.
Franklin is actually a pretty awesome antagonist since he's created an entire test in his father's mansion and able to get ahead of the gang for most of the events.
The Legend of Grimace Island
Ronald manages to transform a ship in a bottle into a fully-sized, seaworthy vessel.
Ronald saves the gang from a giant squid by tying its mouth shut with one throw of a rope.
Grimace manages to prove himself in "Legend of Grimace Island", when, following a failed attempt at stopping them, he courageously manages to force One-Eyed Sally and Blather into surrendering the treasure and leaving. By using a feather and the threat of Tickle Torture, which One-Eyed Sally had previously used on him, no less.
The Visitors from Outer Space
Ronald saving Grimace by hitching a ride on a comet.
Hamburglar is able to outsmart the gang about three times in a row. It is rather impressive for the bumbling Anti-Hero.

Special mention goes to Hamburglar using the doll Franklin gave Ronald to save the planet from becoming infants and toddlers.

The gang being able to outsmart a T-Rex and a group of Western civilians when they end up getting stuck in the past.
The Monster O'McDonaldland Loch
Simon the Monster battling the robotic monster Stiles and Pip created.
The McNuggets' meddling is what set loose Stiles' monster robot loose in the first place, meaning that they gave Simon an opportunity to earn the people of McDonaldland Loch's trust and indirectly caused Stiles and Pip to be arrested by complete accident.
