The first emblem in 100 Acre Wood can be found on the opposite end of the tree house. Cross the first wooden bridge and off in the distance will be the emblem, which is made out of shrubbery/trees.

Near the tree house is a bunch of gardens that the denizens of 100 Acre Wood planted. In one of those is a pretty big pumpkin and the emblem will be on the side of the pumpkin.

For the final emblem in 100 Acre Wood, go to the tree house and look for an empty bucket off to the side of it. The emblem will be in that empty bucket by the clothesline.
