Who are these guys?

It has been too peaceful here! We will need to make some messes to liven things up! We spend a lot of time here in our home and explore it over and over and look for anything that looks different.
We have a lot of interesting places to look, but a lot of things have been here awhile, but they seem to move around the place and we don't know why. Does anyone know who this big guy is? He has been here awhile now but he always stares down at us in the same way! He doesn't seem to be alive, but then all the sudden we find he has moved to a new place in our house here! He looks friendly, but scary too.
Then there is "big orange guy". Who is he? He never seems to move at all! He's been in the same spot for a long time now! He also looks friendly- at least he seems like no danger at all! He would be more fun if he moved around and especially if he played feather with us!
The other odd thing here is this giant water dish! Sometimes it is completely empty- not even water! Then, other times it has a lot of water in it, but we won't touch the water or drink it because it has these smelly pink and orange vegetable matter things in it. We really hate vegetable- especially smelly ones! What is this thing?
Our human companions left us for awhile, but they have come back now. We pretended that we missed them for a few days, but now, all is back to normal. We think they will write about where they were. We are well and happy enough.
The last picture shows one of Ziggy's favorite places to sit. He isn't there now because it takes both of us to make the camera work right! Our humans have not yet figured out that we know how to make pictures! They also don't seem to know that we know how to use the black box that makes these notes! Humans aren't very smart!
