Sound effect didn't go as i wanted to be

[kubieelll]

i'd like to ask for your help.. i'm currently working on my thesis, and i'm making an animal quiz game as my final project. this is my last year too on college. i got lost in track when my animal sound effect didn't add as much as it should be. there should be 9 animal sounds , but there are only 5 that got in. Can you please help me? here's my gdrive link to my godot project https://drive.google.com/file/d/1Ed3xdOP4Bt7066ROxTPJhpdHXs1snQ1j/view?usp=sharing
