Denzil frozen in ice

"Denzil wanted to be cool! So Zaks granted his wish and froze him in ice while he swam. Now he needs your help!"
Nudge 1Where to look
Ice melts. What makes heat?
Nudge 2A stronger push
A fire needs something to burn and something to light it. The first is in the village (third floor, low down), the second is far away, on the grasslands, behind a guard.

Carry the pile of dry straw into Denzil's pad and drop it beside the block of ice (stand left of Denzil, not right next to him: B by him only talks). Later, bring the dry match from the grasslands (The little fellow on the high path) and drop it on the straw. "The hot fire thaws the ice and Denzil is released from his cool jail. He is very grateful and he gives you his flippers."
