Berrykin Bruce specializes in mechanism engineering. Whenever a machine or any mechanical object requires installing or fixing, Berrykin Bruce and his crew immediately arrive to work.
Berrykin Bruce has a talent for inventing complex apparatuses:
- In "The Berry Long Winter" he builds a snow making machine.
- In "On Ice" he makes a mechanism of water show.
- In "On the Road" he builds a "Slinking Slinker Snatcher" trap. The trap works well, though it catches the Berry girls instead of the imaginary Slinking Slinker.
Berrykin Bruce is a "blueberry Berrykin", having a blue themed head with big green eyes. He wears a yellow coverall, yellow gloves and a yellow cap with a sticker of blueberry. Like most of berrykin mechanics, his face and clothes are stained.
- "Bumbling bitterberries!"
- "Well, that is the berry best I can with such short notice!"
- "Put a little muscle in it! Scrub'em good!"
- "Remember the berrykin code: a berrykin never shirks his work!"
- "I have captured a criminal mastermind!"
- "Ed and Earl? Those guys are supposed to be making sure the lanterns don't run out of Sparkleberry juice. If they're shirking their work..."
- (After Ed tells Strawberry to be quiet about berry top secret) "YOU'RE IN ON IT TOO STRAWBERRY?!?! Oh, the shame of it!''
- "How am I supposed to practice my water show here with all these paper decorations?"
- Berrykin Bruce appears occasionally on seasons 2 and 3. On season 4 he appears in two episodes only: "Berry Bitty Adventurer" and "The Berry Bitty Dance Disaster".
- Unlike the other Berrykin mechanics, he wears a hard hat very rarely.
- He is the captain of the Berry Bitty Bombers, the Berryball team of Berry Bitty City.
- Sometimes he works alone, and sometimes he is accompanied by several Berrykins or a whole crew ("The Berry Big Relay Race"), depending how complicated is the task to perform. Among his crew are:
- On three of the four season 3 episodes Berrykin Bruce appears in, his color is green.
