小企鹅去旅行系列 (Little Penguins Travel Series - Set of 4)
The penguin's siblings are on their first solo adventure to visit their relatives in different places, travelling on different modes of transportation and overcoming the different hiccups along the way. One thing that I love about Japanese authors is they are very detailed-oriented! There are just so many details to talk about and each time we have new discoveries! Each character in the stories also has its storyline if you follow closely.
Suitable age: 2- 5years old
