hmm.. i have 98/117 unlocks, i have all trophy's/items except for the final lair trophy, and have all the cones/minigames. do the last 9 unlocks come from beating the final lair?
re Nawel: you have to have wheels on the ground as much as possible for space caves. I sort of bounced from roof to ceiling (turning upside down at ceiling, and pedalling backwards). It can be done.
