Move 2+ columns and your next BONK sets the columns you crossed on fire: the nearest mole on the trail gets BONKed and the holes smoulder for a row. Water puts it out.
BONK it and it rockets into a future row instead of popping: its flame BONKs the first mole it flies past and the landing scorches the holes beside it. Catch it later: +95 per flight.
When bonked, swaps two special moles on screen, then throws a lit torch at the one that landed nearest the strike line (a FIRE BONK that leaves an ember). The crowd loves a trick.
Every ~15 rows one row comes out oily. Strike it, or let any fire reach it, and the whole slick goes up: every oily mole BOOMs. Bombs in oil blast one ring further.
