Give 'im Wot He Wants

Oi! Nothin' smashes nothin' like a giant. Da ones we have 'ere are a big problem, though, 'cause dey keep tryin' t' kill us instead o' bashin' stunties or humies or Ogres. Wot we need is a bigger giant den dey is wot can make dem stop tryin' t' kill us. One o' da boyz said dey saw a real big one out dere in da fiery lands. Dat may be da one we need t' get dese other ones in line. First, though, we gots t' get 'im ta help us. Good thing you're talkin' to me 'cos nobody knows what da giants wants like Murch does! We're goin' ta need some good mushrooms ta start, and I know jus' where t' get some.

Search the area around the crystals to the south for some Slowbrewin' Mushrooms. Gather eight of them. Return to Murch when done.
