You can't "get" him to call you. You just have to wait.
After returning to the sick Pokemon in the light tower (bring your medicine from Cianwood with you).
In SoulSilver, for the second aptitude test, Baoba will call you a day after you have completed the last aptitude test. Not TRUE i tried that once and it did not work so i played for 3 hours and he called me for the second test ( i think it can be on the same day)
i would say soulsliver becase on soulsliver you can fly and black you cacth water pokemon but on sliver you can get fire pokemon
NO
first you have to show warden baoba a sandshrew and wait at least a day.he will call you after the day.^_^
just wait and do jobs for baoba the safari manager and eventurely u'll unlock some and if u do baoba will tell u this is in Pokemon soulsilver
Yes
it isn't anywere
by apokemon event or trade
You need to trade a Chikorita from Pokemon heartgold or soulsliver
the safari zone after baoba calls a couple* of times
Baoba Calls you for the third time when you get the National Pokedex from Prof. Oak. When he calls you he will tell you about placing items. Placing items are not just for aesthetics, but also for attracting rare Pokemon (e.g: 12 water items will attract a lotad). You can get very neat Pokemon which is hard to get. GOOD LUCK
