I felt sad and I felt happy because they were best friends and saved each other lives and they became best friends forever.
My favorite part was when they saved each other's lives because they care so much about each other that they save each other's lives.
I do like the book because in some parts are funny and cool it also teaches you a lesson you never know who you will need in your life.
I recommend this book to people who like adventures and to people who like whales and also to people who like funny books on account of it's funny when the whale throws the mouse overboard. My favorite part was when Amos saves Boris life.
