I will take a crack at trying to crack this egg for them.
Doesn't appear you can even watch it on the home site for the show, Nickelodeon Africa.
http://www.nickelodeonafrica.com/shows/munki-and-trunk/b4v9bsI don't think it is a prosperous IP for them given the little attention and zero mentions it has on the site unless you know it by name. It doesn't appear on their "shows" bar at the top of the site even.
They have an mini site on the production companies website. Sunrise Productions.

https://www.imdb.com/title/tt6044598/episodesThere is a Facebook for the show with only 500 followers.
https://www.facebook.com/Munki-and-trunk-1680680348633384/Strangely when you search "Jungle Beat" you find the same show with 5,000 followers on Facebook. Jungle Beat seems to be another name for the show in certain markets, but it isn't said where.
https://www.facebook.com/junglebeat.tvAnd then if we search for Jungle Beat, we see they DO have an official website.
https://www.junglebeat.tvSearching for the show as "Munki and Trunk" is doing it the wrong way and getting less results. The more well known name for this series is apparently "Jungle Beat."
Some shorts can be seen here.

https://www.amazon.com/Kids-Comedy-Adventure-Characters-Animals-Animation-Allergy-Giragge-Fear-Heights-Tortoise-Tortoise-Animals-Problem/dp/B000B86N1GI cannot find any place to watch the entire series as it has mixed results from Youtube and Dailymotion. You might be able to watch it illegally on one of those video streaming sites, there are many. You could possibly illegally download it on the dark web too.
Hope that helps.
