You don't know Pickle Inspector's number, or if he even has a phone. Besides, your rotary dial appears to have strange symbols on it rather than numbers.

You vaguely recall seeing somewhere the sequence of symbols, STAR - HEART - HORSESHOE. However, you can't quite remember the symbols STAR - HEART - HORSESHOE. You will need the piece of paper with STAR - HEART - HORSESHOE written on it if you wish to remember the sequence STAR - HEART - HORSESHOE.
