Forest 2 is the second level in Croc: Legend of the Gobbos (Game Boy Color).
This level takes place during the night. You will encounter various new enemies here. You'll be using the Jellies a lot as well.
When you find the second jelly, leap on it to grab a key at the very top. Just right is a set of platforms. At the top one is a Cage which you can unlock to rescue the first gobbo of the level. When you have the option to go up or drop down, drop down and continue right to grab the B. After you exit, continue with the upper path until you find a jelly which leads to either a set of three platforms or a single platform going right. Choose the left 3 platforms and grab the O from here.
Proceed into the cave.
