This category covers interactions between characters in Happy Tree Friends, whether friendships, conflicts or romantic pairings.
NOTE: Only relationships between actual characters of the series (not fan-made) may be listed here. Any article violating this rule will face deletion. Also, only official pairings are to be added here. An article focusing on ShiftyxPetunia must only contain their in-series interactions if notable enough and do not attempt to ship them if they never showed felt it on screen, or else it will be deleted because they are not canon with the actual series. Articles will only count if both characters interact frequently in a notable form.
