Postcard: Clockwork Circus

At the Clockwork Circus, strike every column from left to right, hitting a mole each time. BONK the postcard.
How to find it, step by step
- Play CLOCKWORK CIRCUS.
- Do the fair's feat: At the Clockwork Circus, strike every column from left to right, hitting a mole each time.
- A torn postcard drops on the farthest visible row. Only the AUTOMATIC strike collects it: be in its column when it reaches the line. If it escapes it is gone for this run.
- Read it in Fair Book > LORE. All six postcards open the Forgotten Fair.
Reward
A piece of the Forgotten Fair.
