The Dink Network

Hi, yeah I know it's a long time since this was active but I am a bit stuck and don't know of any way to solve where I am. Which is with the dragon for the three trials/tasks. The water and the garden are fine, but I go into the fire one and kill the critters, then when I go near to the lava cone I get "It's red hot!" and when I try to do the active thing I get "I singed my bandana!" or something like it and then "Boo hoo" and it returns me back to the dragon, with the trial not done. Only thing I could think of that might help would be steel skin but I don't have a potion and it seems a bit random that you would need one. Any advice please?
Searched and searched all over the place btw, but the only walkthrough I can find just says about doing them.
Thanks, if anyone can help..
