Board notes 5 details
- Layout
- The yellow car is parked at upper left with its front wheel missing. A flat tire, jack, pump, and tools cover the road; the girl stands by the car and Bubba crouches at lower right.
- Goal
- Inflate Bubba and place his round body over the car's bare front wheel position.
- Opening
- Press and hold Bubba's nose long enough for his body to expand.
- Danger Zone
- Repairing the loose flat tire is a dead end. Bubba must stay inflated before he is moved to the hub.
- Mechanics
- This scene is a mechanic variant of Level 8—Level 8 shrinks Bubba with pinch-in, while Level 42 inflates him by holding his nose.
