Surprise Party

Young Daniel and Wheelie search Autobot records to learn Ultra Magnus's birthday and stumble into danger.

Spike and the Autobots throw a surprise party for Daniel, but it is interrupted by an attack from the Combaticons. Wheelie gets caught in the crossfire and Ultra Magnus throws himself over the boy Autobot to save him from being shot. After hitting the shuttle bay and destroying several ships, the Combaticons retreat. The attack was a coordinated effort by Galvatron to disrupt a peace conference to be hosted on Cybertron the next day.

Daniel and Wheelie want to throw Ultra Magnus a surprise party, but no one knows the date of his creation and it isn’t on file in the Hall of Records. An annoying and clumsy Custodiobot tells them that the information must be stored on the lost Autobot storage asteroid. Daniel and Wheelie steal a garbage ship and head out to find the asteroid and the info. Unbeknownst to them, their movements are being watched by Cyclonus, who evidently doesn’t have anything better to do than spy on garbage ships. Galvatron orders his troops to follow it.

Stuck in a meteor shower, Daniel and Wheelie crash on an asteroid that—surprise!—happens to be the asteroid they were looking for. While they are exploring they are attacked by scaly flying eels and take refuge in a cave, which turns out to be the opening to the records. Inside, sentry robots attack them for asking for the wrong file name. To make matters worse, the eels have found their way inside and attach themselves to Wheelie. Just as they are about to be shot by the drones and eaten by the eels, both menaces are destroyed by Cyclonus and the Sweeps, who take the pair hostage and interrogate them.

Cyclonus reprograms the asteroid into a collision course for Cybertron and then sends Spike a message that he’s holding Daniel hostage. The Autobots have two choices: destroy the asteroid and kill Daniel, or let the asteroid hit the planet and kill all the peace delegates.

Ultra Magnus takes Sky Lynx to the asteroid. The Sweeps attack, but Magnus makes short work of them, then heads after Cyclonus. They pound on each other as Wheelie sneaks by and presses the convenient self-destruct button. Cyclonus runs off and the Autobots and Daniel escape in Sky Lynx as the asteroid blows up.

Safe on Cybertron, Daniel explains how they got into this mess, looking for Ultra Magnus' birthday. Spike declares today as Ultra Magnus' birthday and everyone cheers.
