This achievement can be obtained by simply doing the 'Basic Adventure' mode.
The list of statues in the 'Basic Adventure' mode that need to be done to get the achievement include:
1. Go for it!
2. Dive in!
or instead of doing both of these living statues in the 'Basic Adventure' you can record the First Steps! statue which is the statue you start of with (it is just a statue of an avatar adventurer or an avatar that looks like your Xbox avatar).
After you complete the 'Go for it!' and 'Dive in!' adventure it will award you with a badge and later it will ask you whether you want to record it or not, so click 'Yes' and start recording. If you don't want to do it straight away, that's ok because you can just go to the main menu later and select 'Show off and share', then living statues. Then from there just select a statue you want to record then click 'view' and then record. You don't have to record the living statues straight away.
If you choose to record the 'Dive in!' statue you will be able to obtain another achievement which is called 'Jump the Shark' which is a very easy achievement to get and i think a secret one as well. All you have to do is JUMP and pop there's another achievement.
Also, you can get another achievement called 'Sharing is caring' where you can upload a living statue to www.kinectshare.com which can be done by selecting 'Show off and share' from the main menu, then 'living statues' and from their select 'Upload'. It will take a couple of minutes for it to upload so be patient.
So from these 3 achievements there is an easy 50G's added to ur gamerscore.
I hope this helps and pls give me a thumbs up or down, thks :)
