I saw some nice folks talking about their headcannons, so I thought I’d also contribute. These are all SFW but I can do some NSFW ones if people want!
- Robbie sings in the shower and sometimes Sport sits outside the bathroom and listens.
- ROBBIE DOES SPORTS EYEBROWS FOR HIM!!!!!
- Sportacus isn’t really all that romantic (he doesn’t understand how to be subtle) but one time Robbie came back to his lair and Sport had lit candles and had a record going on in the background omggg.
- NOSE. KISSES.
- NOSE. BOOPS.
- Sometimes, when the kids foil Robbie’s plan, he gets kinda down for a few days bc he thinks everyone hates him and so Sport has to reassure him that he’s loved.
- Robbie has insomnia and it really worries Sportacus a lot.
- Robbie has only ever seen Sportacus angry one time, and it scared him more than anything.
- Robbie does fashion shows for Sportacus.

- Sport totally sees through Robbie’s disguises but humours him because he knows how much Robbie loves the kids deep down.
- THEIR PILLOW FIGHTS ARE LIKE WW3.
- Robbie persuaded Sport to stay up late and play boardgames with him. Sportacus eventually falls asleep and so they both end up sleeping on the floor.
- “Robbie it’s 5 am, have you been up all night making cookies again?”
“Yes but it’s different this time okay!!!”
“They’re for Trixie’s birthday party”
