Before I start talking about episode 10 of Cells at Work!, I want to share something related to it first. Now, we all know that the Platelets are incredibly adorable, but did you know they have their own theme song?
It’s just as adorable as the Platelets themselves, as you might expect.
As for episode 10 of Cells at Work!, Red Blood Cell finds herself in trouble once again, but it is not White Blood Cell who saves her this time around.
The Platelets are still as adorable as ever
This episode begins with Red Blood Cell actually successfully making her way around the circulatory system – and without anyone keeping an eye on her from a distance this time around.
However, this is Red Blood Cell we are talking about. She may not be getting lost anymore, but it doesn’t take long for trouble to find her. Fortunately, there is a cell nearby ready to deal with said trouble, and it is not White Blood Cell.
A mysterious cell saves Red Blood Cell
A cell clad entirely in yellow with a black mask appears out of nowhere, and delivers a swift beating to the antigen that was chasing Red Blood Cell.
Job done
White Blood Cell is late to the party
White Blood Cell arrives after the antigen has been defeated, and tells Red Blood Cell that she was saved by Monocyte. They make up 7% of all White Blood Cells.
Just some Platelets having fun
Red Blood Cell makes her way to the nasal cavity, where she sees other Cells just relaxing – including Monocyte. The same two Platelets she always seems to bump into are present as well, eating.
The Platelets enjoy a snack
After asking the Platelets about what they are eating, Red Blood Cell continues on her merry way. She intends to grab a snack later on, but an event quickly puts a halt to that plan.
Staphylococcus aureus
A horde of antigens invade the nasal cavity. They are staphylococcus aureus – the same type that we saw back in episode 2. In fact, the one eliminated back then is a distant cousin of the current invaders.
White Blood Cell arrives on time
This time around, White Blood Cell and his comrades appear just in time to fend off the initial attack from the antigens. Staphylococcus didn’t invade the nasal cavity without a plan, though.
The antigens fuse together into one giant enemy
The White Blood Cells launch an attack at their giant enemy, but the Staphylococcus aureus has something prepared to deal with the Neutrophils’ attacks.
Staphylococcus aureus uses fibrin to fend of the White Blood Cells
Using fibrin, the antigen is able to render the White Blood Cells attacks entirely useless, and is able to soundly defeat them. Things look bleak for the Cells, but then reinforcements arrive.
The Monocytes arrive
A group of Monocytes arrive on the battlefield, and they have a surprise in store. To fight the antigen, they need to go outside the blood vessel. This means that they will need to change costumes, and reveal their true identities.
Monocytes and Macrophages are one and the same
With the Monocytes revealing themselves to be Macrophages, bloody violence ensues. A few of the antigens flee when they realise just what they are dealing with, and those that remain behind are eliminated.
The Macrophages clean up
A familiar thumbs up gesture
Red Blood Cell struggles to process that Monocyte is Macrophage. She tries to ask Macrophage about it, but Macrophage dodges the question.
Every maiden has a secret or two
That brings this episode to an end, and I enjoyed it a lot.
Fans of the cute stuff will be happy to see the Platelets again, and we got some good action courtesy of the Neutrophils and Macrophages.
There was plenty of good humour to be found in this episode, of varying type. The slapstick moment of White Blood Cell having the grate fall into his head was amusing, and the Staphylococcus aureus family tree got a laugh of me, too.
If you asked me to pick a favourite cell from this show, I’d probably have to say Macrophage. So violent, yet so elegant at the same time. It’s a great combination, and having them be the stars of this episode ranks it among my favourites. This episode is right up there with the Cancer Cell episode.
This episode adapted chapter fifteen of the manga. Red Blood Cell’s solo journey around the circulatory system and the cells relaxing at the nasal cavity were extra additions for this episode.

The platelet song did the rounds on Twitter and I really enjoyed listening to it. Thanks for sharing.
