Lieutenant Joseph John Lemmiwinks

Lieutenant (Formerly Sergeant) Joseph John Lemmiwinks or "JJ" for short was Captain Callum's sidekick who appeared in the series "Captain Callum's Adventures". He first encountered Captain Callum when he is caught sleeping in Captain Callum's improvised bed. In the third episode of the series Captain Callum hires him because his ratings are low and he thinks that helping out a homeless man by giving him a job will make himself look good.

In some episodes he is seen to have a strange attraction to trees as he is always distracted by them. In the episode "Saving Captain Callum ft. JJ" it is implied that he has some sort of Tree Fetish.

In "Promotion ft. Captain Callum (& JJ)", he is promoted to Lieutenant as Captain Callum feels as if he deserves it. In this episode him and Captain Callum discover a magical stone (the same one from The Supercat Video Universe: Volume 2) after it teleports to their dimension after Jamie in the video universe knocks it to the ground causing Mullac to lose it.

The stone being unstable creates a black hole type portal and begins sucking everything into it, JJ being the only unfortunate victim to be sucked in, leaving Captain Callum to host the show on his own. This is the last appearance of JJ as the portal ultimately killed him.

In "Bill's Distraction" his hoodie is caught by Bill after it enters the Video Universe dimension with the stone after it returns there.

His death is also brought up in "Captain Callum Explores The Universe".
