Overall, the series had 5 title card backgrounds for its episodes, each to a correspondent season:
The first one features a Troll hair-like spiral, and was used in Seasons 1 and 2.
The second one shows a hill with two small plants. It was used in Season 3.
The third one depicts another hill with a number of mushrooms. It was used in Season 4, except for the episodes "Three Trolls-Keteers" and "The Helper", which had the previous background instead.
The fourth one depicts a series of pods hanging from trees. It was used in Seasons 5 and 6.
The fifth one has yet another hill, but with a pond-like nature. It was used in Seasons 7 and 8.
The title cards of the series' episodes indicate what Troll Tribe is their focus. For example, "Kick-Off Party" focuses on the Rock Trolls, and therefore has a Rock-themed title card. Meanwhile, "Bring It In" is based around the Classical Trolls, and thus has a Classical-themed title card. The title texts are also stylized like the Trolls Logo, unlike the ones of Trolls: The Beat Goes On!. In later seasons, there were episodes that broke this rule, for example, "The Party Switcheroo" is labelled as a "Classical" episode but is merely set in Classical Crest - it stars Val Thundershock and Smidge.
The Pop-themed title card features a landscape similar to the ones featured in the title cards of Trolls: The Beat Goes On!. The title text is colored in a pale shade of blue. The Pop Tribe had the most episodes dedicated to them, at 42.
The Rock-themed title card depicts a number of speakers, wires and lights. The title text is in lavender. 16 episodes were dedicated to the Rock Tribe.
The Country-themed title card shows a rising sun alongside a sea and some rocks. The title text is in a mix between bright blue and purple. 16 episodes were dedicated to the Country Tribe.
The Classical-themed title card depicts a number hair-like sculptures on a golden floor. The title text has a golden color. 12 episodes were dedicated to Classical Tribe.
The Funk-themed title card shows a rainbow splatters on a black background, with a purple light in the center. The title text is colored mint green. 10 episodes were dedicated to the Funk Tribe.
The Techno-themed title card features a number of corals in an underwater environment. The title text is a mixture between cyan and lime green in color, and has an ocean-like pattern put onto it. 7 episodes were dedicated to Techno Tribe.
There were no Techno-themed title cards for episodes of Seasons 2, 6 and 7.
No title cards for any hinterland Trolls were made and featured over the series' airing.
