Tambourine Attacks!

Goku finally catches up to the creature responsible for Krillin's death. The monster introduces himself as Tambourine, one of King Piccolo's demon offspring, and openly boasts about killing Krillin for his Dragon Ball and the tournament fighter roster. Exhausted from the tournament and running on fumes, Goku is in no condition to fight.

Tambourine destroys the Flying Nimbus with a devastating mouth blast, sending Goku crashing into the forest below. Despite Goku's attempts to fight back, including using the Power Pole, Tambourine overpowers him brutally and leaves him for dead in the woods. Meanwhile, back at the tournament, the group decides to bring Krillin's body to Kame House and regroup.

Returning to Pilaf's airship, Tambourine receives new orders from King Piccolo: hunt down and kill every martial artist on the tournament roster so that no one can ever use the Evil Containment Wave against him. Tambourine wastes no time, traveling to King Chappa's temple and killing both the champion and his students, then intercepting Pamput during a kickboxing match and ending him as well. The episode closes with Goku lying motionless on the forest floor.

The destruction of the original Flying Nimbus is a gut punch, removing one of Goku's most iconic possessions permanently. Goku's defeat at Tambourine's hands is one of the most lopsided losses in the series, made worse by his weakened state after the tournament.

Tambourine's systematic killing of tournament fighters, including fan favorites King Chappa and Pamput, raises the body count and demonstrates that King Piccolo's reach extends everywhere. Master Roshi's examination of Krillin's body reveals the cause of death: a single devastating kick to the skull.

This episode delivers Goku's first truly crushing defeat and strips away his main mode of transportation. The Nimbus cloud that carried him since his earliest adventures is gone for good. Tambourine's rampage across the world establishes King Piccolo's forces as a global threat, not merely a personal enemy for Goku to settle a score with.
