Jelly Jamm (Singaporean English dub)

A Singaporean English re-dub of Jelly Jamm has been known to air on ZooMoo in Asia since 2020. The show itself premiered on January 21, 2019, but in the original version with British voice talents; it was phased out on Asian ZooMoo feeds in favor of the redub the following year. It still airs to this day. The dub is likely a production of Beach House Pictures, specifically their Beach House Kids division, the Singaporean studio behind the majority of ZooMoo's content.

Despite the show being originally in English, a redub was produced for audiences in Singapore, likely to promote proper development of the English language among Singaporean youth. Standard Singaporean English, which is used as a "target" form of English for Singaporean youth to learn, "generally resembles British English and is often used in more formal settings such as the workplace or when communicating with people of higher authority such as teachers, bosses and government officials," as stated on Wikipedia.

The characters speak with generally British-sounding accents, representing a "target accent" that Singaporean children should aim towards learning to speak with. The line delivery of the characters varies from the original, and speech is often far more annunciated and articulated to make every line clearly heard. However, the distinctive lisp of Goomo and muddled foreign accent of Mina in the original are not used in this dub, considering as they might hinder proper language development. Instead, Goomo always uses a standard /s/ sound and Mina's accent sounds slightly Irish, keeping her "foreigner" flair without making it deviate too far from British or Singaporean English.

In late November 2021, the Singaporean English dub was added to Sensical, a children's streaming app. Despite being labelled as "Jelly Jamm español" in the app, the audio is Singaporean English only.

Script modifications
Since Jelly Jamm was originally produced in British English, the episode scripts have not been modified from their original forms for the most part. However, there are some minor edits made to some episode scripts. This list seeks to document all the known line changes in the dub:
 * Instances of "Yeah!" are replaced with "Yes!" in some episodes such as "Silent Sheriff" and "Back Up."
 * In "Rita Adopts a Dodo," Jellyberries are referred to as both "Jellyberries" and "Dodo Beans."

Cast
The cast of this dub is currently unknown. Dubbing credits are not provided; rather, the original credits with the British voice actors are shown.

Trivia

 * "Let's Go Together!" has been re-cut for this dub, being trimmed from the long version of the song as opposed to using the pre-made short version used in the original and other dubs which utilize the English intro. This re-cut of the intro only appears to have been used in early episodes in season 1, though; later season 1 episodes (post-Flying Lies) and the entirety of season 2 use the original intro.
 * Insert songs are not re-cut or dubbed unless they are an episodic song performed by a character. For instance, Goomo's Sidekickman jingle in "Radio Goomo" and the "Flying Bathtub Rap" have been dubbed.
 * A snippet of this dub appears in ZooMoo Asia's 2020 ad for their holiday specials, which confirmed that the dub is aired throughout Asia.
 * A now-deleted YouTube video posted in June 2019 showing the Philippines feed of ZooMoo, broadcasting the episode "Sound Detective," showcased the characters' original voices as opposed to their re-dubbed voices, proving that this dub was not always aired on ZooMoo. ZooMoo's most recent sizzle showreel, created in July 2020, also features Bello's original voice, which proves that this dub begun airing post-July 2020. However, the exact date it began to air is unknown.
 * The pronunciation of Mina's name is kept as "Mih nah" in this dub.
 * Due to having older male voice actors in the dub, Bello and Goomo have significantly lower voices.
 * There is a possibility the existence of this dub has some ties to the Singaporean government's "Speak Good English Movement," which promotes the use of proper grammar and accents among Singaporeans, though this cannot be confirmed.
 * Alternatively, there is the possibility that this dub was produced and began to air for a similar reason to the English re-dub of Adventures from the Book of Virtues, also produced in Singapore; to avoid paying royalties to the original cast. However, since the cast of this dub is completely unknown, there is no way to confirm this.
 * Ongo is the only major character in the dub to have not been redubbed.
 * In the UK, some episodes of the dub can be streamed via Virgin TV. Its on-demand section for Jelly Jamm features a blend of episodes of the original and the Singaporean English dub.
