1. Collected paintbrushes.
2. Found random objects all the time.
3. Had its own tinier pet.
For once, don't you just wish your pet could feel the same stress and sense of responsibility that YOU feel taking care of it?
4. Went on quests.
Basically another (albeit risky) way that your pet could potentially be earning you money, but isn't, which is a shame.
6. Ran a shop.
7. Battled other pets.
Uhh, alright, maybe not this one either.
8. Shamelessly begged for money and food.
9. Got you involved in pyramid schemes that were explicitly against the terms and conditions of owning said pet.
Ugh, don't you wish your pet encouraged you to accept offers from other pet owners to buy items for way over their value in exchange for cheat codes and rare items, which you are totally willing to do because you're DESPERATE? So you do it, but you end up getting your account frozen? Wait, this is actually a hyper-specific situation and I'm not sure how to relate it to the real world at all. Forget this one.
