This achievement is awarded for obtaining the Solar System Costume, pretty much the ultimate costume of the game.

To get this, Wait until near the end of the game after getting Oral in your party. Talk to the kid in the basement with the portal and use the Jefferson costume on him to obtain a mysterious candy. This can be planted in the soil nearby. Warp to the future and notice the tree has grown slightly.

Head out into the Dental Compound and talk to the gardener on the right side near the research centre. Talk to him, then use Jefferson on him. After that make sure your party is wearing Hot Dog, Superhero and Wolfman then talk to him again to remind him of the movie he forgot. Continue to talk until you get the fertiliser.

Warp to the past and use the fertiliser on the tree seed. Back in the future the tree will now be huge. Head to the back door of the research centre and onto the compound walls. Head down and you'll see a secret door on the huge tree. Bash it open, head up the really long ramp and at the top you'll find a chest with the costume!
