幾個英文文章的問題 - 寵物

上下文是說 自己照鏡子練習臉部肌肉放鬆

Q2 想請問CAT的引伸意義

"A bag of smelly rocks? These smell like... Hawaiian seaweed! Best (insert holiday) ever!"
Q3 Hawaiian seaweed 這是一個東西嗎?還是節日呢? 有點不懂後面的意思

Q4 上下文是說 收到禮物時就給對方一個大大的擁抱 即使只是一雙襪子,然後後面的引文有一點不懂,講個大概即可謝謝

不好意思 還有一點小問題想要麻煩你一下

後面那句是有點接近東窗事發的意思嗎 還是有別的意思呢?
感激不盡!!
