Chibi-Robo! features some little references to the Mario series, specifically:
- During the day, the clock on the upper left corner of the screen shows a sun. This is actually the same as the life meter from Super Mario Sunshine, only mirrored and rotated. During the night it shows a moon designed in the same style.
- The Princess Pitts character is likely based on Princess Peach, given the similar name, appearance and role, since they both are damsels in distress.

One of the unlockable costumes that Mario can wear in the game by using a Mystery Mushroom is based on Chibi-Robo, and it's unlocked in the 100 Mario Challenge mode or alternatively by using the Chibi-Robo amiibo. When worn it replaces the sound effects with sounds from the original Chibi-Robo!.
Super Mario Odyssey

This game features compatibility with many different amiibo, that when scanned will be recognized by Uncle amiibo and called by name. This includes the Chibi-Robo amiibo.
This creates a sub-universe link with the Yoshi series because Uncle amiibo says the character's name out loud within Mario's universe, it's not just an on-screen message.
Copyrights for both series are held by Nintendo.
