Random radish

Hi everyone, did a search, but radish is a very common word!

Just pulled some radishes from the plot, all seeds from the same packet.. pulled 4 lovely round red ones, and one much larger very odd purple one  Cleaned them all under the tap before we bought them home, and by the time we got home o/h had a blue hand..
anyone got any ideas what this random radish may be?

Purple plum?

I grew these this year and they were much more purple in colour than the online pictures 

Definitely wasn't a beetroot yorkie - the leaves were definitely of the radish variety, and when cut into the flesh was white, and o/h confirmed it tasted like radish (personally can't stand the things but he loves them!)

was it this one?

was it this one?

Don't think it was that one mum, but can't be sure When I pulled it, i just thought it was bigger and slightly darker than the rest, it wasn't until o/h washed it & bought it home that we realised it was a completely different colour... guess I need to be on the look-out for more randoms and take a photo before they disappear down o/h's throat!
