Woah, kudos for the post man! To fill you in, Mondo TV has also incorporated SEK's animations on two others shows:
Animal Games and
Happy Adventures. Unlike the three you mentioned (
Bugs Adventures and
Toy Toons have stop-motion animation and
Great Book of Nature has animation featuring at least one animal character), these two don't seem to have any particular theme. The prolific Italian company has also adapted two feature films,
Prince Moon and Princess Sun (호동왕자와 락랑공주) and
Young Fisherman & Black Dragon (
어부총각과 검은룡), in English.
The funny thing about
Animal Games is that it uses the
Great Book of Nature intro and outro, except now there's a Korean title(!!) instead of the English one in front of the hardcover book, and the English dialogues are re-dubbed; some of the voices are more obnoxious.

Also, in all these shows and films that have in-house North Korean animation dubbed in English, all original music is replaced by compositions of John Sposito, Italian composer who has worked on numerous Mondo TV originals. I assume they did that partly maybe because they couldn't obtain the dialogueless audio due to the original masters' age. Music of him that's heard in these, has also been used in newer Mondo TV productions, such as the
Cat Leopold reboot. (for those of you wondering what this CPM Cinematografica company listed under "Music" in the end credits of some of these shows, I scrutinized the web, and I believe it's John Sposito's music publisher) The only adaptation that retains the original soundtrack is
Little Bear.
The video in a few of these Mondo TV distributions is worse than in the original version, from what I see; take for example a look at Young Fisherman & Black Dragon (in Korean). The first is a rip from KCTV and the second one is an upload from one of the YouTube channels that distribute Mondo TV material (Little Bear is also available in Korean on the
Asian Mondo World channel, meaning that Mondo TV also holds distribution rights to the productions in their original language).
A short production that in my opinion stands out from the rest is
새로 사귄 동무 (2004). It was included on
Happy Adventures as episode 9, under the title Animate Toys. Since it's SEK's first computer-animated short and revolves around toys, I guess it's a rip-off of
Toy Story. The Korean title also translates to
A new companion.
As far as voice acting goes, these dubs are the equivelant of 4Kids's anime dubs. However, unlike 4Kids, the folks over Mondo TV are so cheap that they don't even bother to localize the on-screen Korean text. Also, the only two adaptations where there are detailed end credits (that mention in great detail directors, animators etc.) instead of the usual Mondo TV ones (which list Matteo Corradi as planner, Valentina Maselli as script writer, Gian Claudio Galatori as production director etc.), are
Little Bear and
Prince Moon and Princess Sun.
The one of these productions I have watched a lot is
Great Book of Nature. It's a pretty innocent and colorful show to watch every once in a while, though the pacing may bore the audience.
