...You can always try again.
At growing up, that is.
Here we have a particular Orca-mer from one of the regular Ark issues, who re-encounters the Arkuaticans. Feeling bullish, Dill decides to try and torment them again. Big mistake.
This comic isn't canon, but I do like to imagine scenarios where every few years he turns up, unknowingly or unwillingly and ends up getting the shrink treatment again.

This is the last page in the Ark comic 'Rich In Omega 3' But if you think you'd like to get in on the Arkuatica comics available, Become a patron.
