The anime focuses on a dog named Hanamaru and his animal friends in Guru Guru Town, enjoying their lives together.
Provides examples of:
- 2D Visuals, 3D Effects: The opening scene in the superhero segments always consists of the birds (which are 2D animated) in a CGI rendition of Guru Guru Town.
- Amazing Technicolor Wildlife
- Big "NO!": Shimao does this twice in episode 84 when the boys misunderstand his views of executive business, complete with him turning into a poorly drawn version of himself.
- Christmas Episode: "The Old Christmas Tree/Christmas Eve/Hanamaru King Deluxe: It's Time for Revenge!"
- Clip Show: Episode 88 consists only of superhero segments from previous episodes.
- Conspicuous CG: The intro to the "Song Corner" segments beginning with episode 26 is entirely done in CGI.
- At least one episode has a brief scene done in CGI, using the same Hanamaru model as the example above.
- Deadpan Snarker: Shimao has his moments, despite his otherwise friendly personality.
- Eye Catch: This anime has all sorts of eye catches after another between each segment.
- Gratuitous English: A few of the bridging scenes during episodes have Yuuho-san and/or the mushrooms saying English phrases.
- A scene in episode 84 has Shimao teaching the boys "Business English", which is nothing but nonsensical phrases.
- Inelegant Blubbering: The girls all have had their moments, but Maruru takes the cake.
- Shimao also does this during the Hanamaru Prince segment in episode 15.
- Saturday-Morning Cartoon: TV Tokyo broadcasted it on Saturday mornings at 7:30 beginning on April 29, 2001.
- Sick Episode: "Mom is Ignoring Me". Hanamaru wants to intentionally catch his sister Maruru's cold to get attention from his mother, but then decides to catch it from his friend Shimao instead.
- Slice of Life
- The Song Remains the Same: All foreign dubs except for the Valencian dub do this.
- Subverted with the European Spanish dub. Only the opening and the first ending are dubbed, while the remainder of the songs are left in Japanese.
- Toothy Bird: Penpe (a penguin) is shown to have teeth at certain moments.
- Valentine's Day Episode: "Valentine". Downplayed by the fact it's paired with two regular segments.
