Guysap

hey friends today I will show you a new animal that I have seen for the first time in my life.
It looks like Guisap but sometimes the color of this animal is changing. So I don't understand what an animal it is.
I found it in a forest next to my house. This creature has a large nose, it will be about one foot high.
I put this animal in a cage, but this animal broke the mold.

I do not understand what animal you must tell me if you know this.
