 If you liked Yotsuba to! |  ...then you might like Shinryaku! Ika Musume |
Curious cute little girl doing cute stuff in the strangest way possible is the premise of these comedy manga both catering to the male demographic (whether Yotsuba is seinen or shounen is still arguable so let's generalize that). Art in both are greatly similar to one another - simple yet appealing.

Both series represent slice of life with creative fun and a lighthearted atmosphere. Although they deal with a different premise, both series consist of a wonderful cast of characters with sincere comedy. The every day events and interactions these characters formulate moments that you can't help but smile. Shinryaku Ika Musume adapts more fantasy tropes while Yotsubato takes on a realistic route with its direction. Recommended for fans of slice of life.
