How to replace objects that not are the dog?

[riverking]

I need to know the codes to replace items, Like this (this one replaces the dog of the clock Town in Majoras Mask (U) !).

8154E6DE XXXX
8154E7B4 YYYY
8154E7C2 ZZZZ

If is possible, I need to know how to find the codes of other objects.

Thank you very much
