Gonna be honest, I don't really see that Roobarb and Bigger Brother are all that similar. I mean, if you squint (a lot) there's a sticky-up bit on the front of each flipper which gives it a (very) passing resemblance, and that's about it- different body-shape, different armour, very different level of effectiveness... Each to their own though I guess.
