Any pets aside from Dragon that give special effect?

I was curious if there were any other pets out there that gave a special effect for equipping 3 pets at the same time. Would Robo do the same if you have at least one evolved pet (similar to the dragon)? What about donor pets?

I have 3 snowmen out on my bishop but I never get any winter effect (even after taking off all my nx that could potentially clash with an effect)

 

I think the snowman in royals is different from the one that gives the effect. A guildmate has 3 penguins and has the effect.

 

Does anyone know if the Yeti Robo counts for the effect?

 

Unlike dragon, i had to evolve all my robo pets to get the effect.

 

i hv snowman + reindeer + penguin giving me the effect

can u take a ss of this?

im getting the effect with just the normal ones

 

Didn't work for me few months ago, but now that i clearly think about, it was probably because one of the pets was evolved before i bought the other two, once i evolved them the effect worked properly.
