Legends of Spark Season 1 Episode 27 Birthday Panic

It's Spark's birthday, but Flash is nowhere to be found. The repair shop receives a mysterious package, which when opened appears to be a ticking time bomb. Everyone panics, but Spark steps forward to take it outside the Tyretown city limits. As he rushes to the outskirts, the timer runs out, and the "bomb" fills the sky with celebratory fireworks - a birthday present for Spark from Flash.
