Easter eggs, apart from a chocolate treat at Easter, are items hidden within games. SotC contains many easter eggs all of which I have tried to list here and instructions on how you can find them.
Ico - If you’ve completed Ico and the save game file is on the same memory card as your SotC game file then Agro will display a small ‘i’ on his for-head instead of a diamond shape.
Doves - Every time a Colossus is defeated an extra white dove appears around the alter in the temple.
Petting - If you pat Agro by pressing the circle button with no weapon equipped (you can do this either standing next to her or sat astride) your stamina is replenished twice as fast.
White Agro - When SotC has been completed on the hard mode more than 4 times a white Agro will be granted to you permanently.
Climb Trees - The trees dotted around the landscape can be scaled by climbing up the green moss on the trunks.
Fruit - The trees contain fruit which can be dislodged with an arrow and eaten. This increases your health.
Crouch - Your health replenishes twice as quick when Wander crouches.
Food of the Dead - The fruit in the trees of the secret garden is poisonous and takes life instead of giving it, reducing your health.
Obscured - When your stamina reaches such a large level the gauge becomes ghosted to prevent it from obscuring the screen.
Zorro - To make Agro rear up and gallop from a stand still, pull sharply down on the left stick when tapping X.
Wild Riding - It is possible to grab the wildlife such as the doves in the temple, the eagles on the plains and the fish in the water by holding down R1.
White Tailed Lizards - White tailed lizards can be found on every save point and their tails increase your stamina when collected. You can either kill the lizard to collect the tails or for an even harder challenge, shoot the tails off the lizard with an arrow without killing the lizard.
White tailed lizards are not only found on save points. They can also be found along cliff walls hidden within crevices. They are sometimes hard to find and patience is required to locate them. Agro actually scares them away but you can make Agro run away by aiming your Bow and Arrow at her(don’t shoot her, it’s cruel).
The Secret Garden - The secret garden can only be accessed via the vines of the south eastern wall. You will need a lot of stamina to be able to get to the top beyond the gate located at the top of the spiral walkway at the end of the hall of the temple. I wouldn’t recommend attempting this until you have the cloth of desperation as a high fall will kill Wander.
Reminiscence Mode - Defeated Colossi can be re-defeated in a mode called Reminiscence Mode. Simply find the ‘corpse’ which will be located wherever the Colossus was slain and prey at the foot of the corpse. This will replay the Colossus from the moment it was found, but with all your ‘powers’ reset making the challenge harder. It also provides a nice ‘memory’ effect where everything is sketchy, like an old film.
Circus Tricks - Wander can perform great feats on Agro. Press and hold R1 and X while galloping and he will stand up on the sadle. Agro can be steered but not stopped while performing this acrobatic.
Quick Turn - Agro can perform a quick 180 degree turn. When galloping, simultaneously, and sharply, press down on the left analog stick twice and the X button twice. Agro will stop and turn around to run the other way.
Emergency Stop - Agro can also stop quickly while galloping. Simultaneously press down on the left analog stick and the X button.
