Who do you throw your pinap berries at? Why?

Dratini of course & Swinub they are rare here

Dratini, a dragonaire (within reason), low CP useful mons, pretty much every Magikarp.

All starter Pokémon and rares like Dratinis.

Everything I come across that is rare, magikarp I only see like 5 times a month tops so those, also seel and omanyte, starters etc.., I've lost a few totodiles but gained enough for a feraligatr and then some, in 2 weeks at a spawn point

Dratinis, Larvitar ( if I'm ballsy Pupitar only seen 2 though), Rhyhorn, and Mareep( if they are a low enough level)

Usually on pokemons which i need to evolve or rare to see.

Most of my berries and Pokeballs were given to Murkrow whose flee rate of the first and second throw is 100%. However, this Pokemon is totally bootless even up to the 40 level. Now I get 336 Murkrow candies which is a waste. I hope the Murkrow could be designed to evolved to other 3000 CP things at level 40.

So far, I've used them on Magikarp, Squirtle, Dratini, Abra, Bulbosaur, Rhyhorn/Rhydon, Slugma, and Sunkern.

Moving forward, it'll be Magikarp, starters, Dratini, Abra, Rhyhorn/Rhydon, and Slugma (still need to evolve).

Primarly starters and rare stuff like Dratini's, but depends on their CP level.

Eevee, magikarp, rares like dratini or omanyte, and some low CP evolved forms. Low CP evolved Pokes are always tempting to pinap thanks to their bonus candies, but which ones I go for varies depending on how many pinaps I have.

Pidgeys. Seriously. I'm evolving them so many of them that this level (35) is just flying by. Well, in relative terms that is. :-)

magikarp (preevent/postevent), low cp ryhorn, growlithe, grimer, larvitar, dratini, machop, pinsir... usually pokemon i dont have much candy of or need more for planned evos/pushing. caught like 4 dratinis (of ~6 seen) and 1 larvitar (only wild ive seen yet) with pinap so far, one dragonair ran away, but i think its worth the risk. also caught two blastoise (the 160cp was harder than the 1400cp) with pinap, just for science... didnt really need candy.

stuff I want to evolve but are uncommon for example magikarp and chinchou. rare stuff I won't take the risk and will use razz instead.

I have quite a few, but honestly i would never use them on a common Pokémon like Magikarp. I have used them on: Dratini, cyndaquil (not common here, and I wanted a Typlosion), mareep, Snorlax (disappointed in a 300cp but at least I got the candy), Dragonaire (usually too risky because they're hard to catch, but I encountered a 150cp), and most of all -Larvitar.

I have used 2 or 3 on common Pokémon that were 3rd evolution. Today I saw a 150cp Pigeot, so it was worth a Pinap to get 20 easy candy. Same with a 300cp Magnanium.

Rare mons that I want to evolve.

Magikarp, pokemon i still need cabdy for to evolve them (if the encounter has low enough cp)

On stuff that I want more candy to power up or evolve, rare pokes like, dratini, larvitar, machop, uncommons where I am fishing for a specific move set like chinchou, houndour, teddiursa, ...

I had balls enough to use it on a Lapras

Only rare stuff, never common Pokemon for extra leveling oomph. After a while, the XP really starts to be a nonissue.
