I Can Lick 30 Tigers Today! features three stories: the book's namesake, King Looie Katz and The Glunk that Got Thunk. Each are told in the same tone you'd expect from Seuss with a good measure of silliness for fun. This isn't an I Can Read! early reader's book, so a really young child would still need assistance with these stories.
I Can Lick 30 Tigers Today! showed its age with the main character occasionally saying he could "beat up" the tigers. Would a modern Childrens' book contain something like that today? I'm doubtful. It caused a little confusion because I thought he was trying to lick them, but whatever. Maybe I'm trying to apply too much logic to a Dr. Seuss book which is obviously ridiculous. Still, I ended up enjoying the book as a whole and it brought on some sweet, sweet nostalgia!
My personal favorite of the three was The Glunk that Got Thunk because it's perfect for reading out loud, made up words and all. Recommended for kids and adults of all ages!
