The rare items list has been hugely helpful, and I used the old posts to find a ton of missing stuff, but there're still four that elude me. If anyone can point me in the right direction, I'd be very appreciative.

Oh, and I do have the DLC, by the way.

Sound
Guitar, 1-1-1 (1m10cm9mm) FOUND!

Containers
Kerosene Tank, 1-2-3 (79cm5mm) FOUND!

Decorations
Program Name, 4-1-4 (2m60cm9mm) FOUND!

Flowers
Rafflesia, 3-2-1 (1m49cm5mm) FOUND!

Thanks for any help anyone may be able to offer!

i can't check tonite but i will do my best to look tomorrow.

The Rafflesia is in the fountain in the garden area of the rich house in Dynaville.

It also seems to me that I remember seeing a Kerosene Tank in Roller Roaster, but I wouldn't swear to it.

there's a guitar in fancy's, on the wall near the spinning princess, if you were going to climb the shelf and head to the left to get where the steps are. in that area.

there's a kerosene container in sunrise. you know little fenced in area where the dog house is and the burglar in the outside area near where you come out of the candy store? well, the container is behind the doghouse near the burglar. you need to get big enough to roll up the fence before you can get it. but i was able to get it there.

the program name is in the tv studio in seadome.

hope this helps. :)

Thanks much, guys! With your directions, it only took me about 15-20 minutes to run through the last four items. There was a momentary panic when the achievement didn't unlock, but then I realized the vault needed a few more levels, but that was easy with the FAQs. :)

Thanks again!

congrats. *cheers* let us know if there's anything else you need help with.
