Reader's Digest 6月号の記事 "The Teacher Who Wrestled A Cougar" からの引用です。
Now the cougar could see the funny little creatures that had been making all the noise. These were perfect prey: small, wiggly, and oblivious.
ピクニックに来ていた子供達（the funny little creatures）の様子をクーガーがうかがっている場面です。
"oblivious" は "oblivion" と関係がある単語の様ですが、 "oblivion" は忘却としか覚えていないので、ここでの意味が分かりません。辞書を見ます。
・Oxford English Dictionary: Not aware of or not concerned about what is happening around one.: she became absorbed, oblivious to the passage of time
・Collins English Dictionary: If you are oblivious to something or oblivious of it, you are not aware of it.: She lay motionless where she was, oblivious to pain.
・Cambridge English Dictionary: not conscious of something, especially what is happening around you: Absorbed in her work, she was totally oblivious of her surroundings.
