You can find four bears on the far right side, where you must build three bridges to reach a patch of land. Once there, you can find four different bears that can be picked up and moved. You can then arrange the bears in a 2x2 square, with the bears in the following positions:

Secret Bear: Top-left
Covert Bear: Top-right
Enigmatic Bear: Bottom-left
Discreet Bear: Bottom-right

Once they are all in place, they will turn into a giant bear statue.
