I'll find a way

I saw the lines below from the movie called A street cat named Bob.
I know, I know you’re hungry, buddy. I’m sorry. I’ll find a way, okay. I’ll find a way.

I’d like to know if I can use other phrases such as “I’ll figure it out” or “I’ll work it out” instead of “I’ll find a way”. Does it sound weird? How about “I’ll do something about it”?

Thank you!!

Those all sound fine. “I’ll do something about it” changes the meaning slightly, though. It could imply that he’s already found a way to address the issue.
