What was that fourth thing?
1. The bu(**) from a cigar.
2. Filter from coffee.
3. A piece of blown tire.
4. ?
Also, in which order was Sonic switching these things when Robotnik was not looking, since the list above this thing refers to the time when Tails has made reference to these things instead of the process of the switch?
