Cloaked Frog
The invisible (or cloaked) frog can be found in the 'Below the Thunder' level, just after you get off from the big yellow elevator that takes you up. To find it, as soon as you get off from the yellow elevator you will come to a room. Look at the roof and you will see a metal grate. Shoot that and jump up into the hole. Once in the vents, keep taking lefts till you get to a dead end... he will be sat on a red book 'Croaking while Cloaking'.

Adapt Or Perish: Frog
Get to the part after losing sight of Lee for the second time during the pursuit and reaching the KPA Nano-Suit soldiers fighting an alien exosuit. Go to the right and walk up the hill with a resort bar on top. Inside the bar, enter the larger of the two bathrooms. On the toilet you will see a frog frozen to a book. Upon picking up the book, Psycho will exclaim, "It's Calmon! I've found him!" Once the book is thrown or dropped it will explode.

Frozen Paradise: Ice Age reference
After escaping the frozen aircraft carrier you will enter an ice cave. Near the entrance, look for a hole near the ceiling to the left. Jump up into this hole and stay on the second level of the ice cave. After jumping across a gap, look along the left side of the ice cave. You will find a rat and acorn frozen into the ice. This is a reference to Scrat the saber-toothed squirrel from the movie Ice Age.
