Opal Goodbody, who is helping organize Lobelia's upcoming party, has been bothering Holly Hornblower to deliver a pie for the party.
'Lobelia Sackville-Baggins has been fussing and bothering everyone about this party of hers for a while now, but evidently that wasn't enough for her, so she's brought on another hobbit, Opal Goodbody, to help her.
'Poor Opal has been so harried by Lobelia that she's snapping at everyone. She's been after me for a pie, but being not too fond of Lobelia, I've put it off. But I couldn't put it off any longer, so today I made the pie she's been after.
'The pie is cooling on the table over there. Take it up to Opal at the Party Field, but remember: even though this pie is for Lobelia, it must be hot when ye deliver it! Keep it away from those hungry hobbits... I don't want them pestering me!'
Opal Goodbody is at the Party Field, north of Hobbiton and south of Bag End.
When you returned from delivering a pie to The Green Dragon, Holly Hornblower had another delivery task waiting for you: she has asked you to take the pie she baked for Lobelia Sackville-Baggins's birthday party to Opal Goodbody at the Party Field in Hobbiton, south of Bag End and north of the town proper. Make sure that no hungry hobbits catch a whiff of the pie, or they will be pestering Holly for a slice!
Holly Hornblower can be found north of the main square of Hobbiton and south of the Party Field.
When you delivered the pie to Opal Goodbody, she tasted it and found that it tasted awful. She demanded a new one from Holly Hornblower. You should return to Holly at once.
