mysql2 in rails3 'table exits already' how to delete that?

Question

I delete the project robin_offine for some reason and when I restart it and run

rake db:create,it claims:

robin_offline_development already exists  
robin_offline_test already exists  

ignore that and add migration named events

if rake db:migrate

Mysql2::Error: Table 'events' already exists(cuz i have done that last time)

The problem is ,I couldn't find where the table is

SHOW DATABASES;  
+--------------------+  
| Database           |  
+--------------------+  
| information_schema |    
| test               |  
+--------------------+   
2 rows in set (0.00 sec)

Even don't know which one to delete

sorry I'm new to mysql
the system is Ubuntu 12.04LTS

development:
adapter: mysql2
encoding: utf8
reconnect: false
database: robin_offline_development
pool: 5
username: root
password:
socket: /var/run/mysqld/mysqld.sock

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: robin_offline_test
  pool: 5
  username: root
  password:
  socket: /var/run/mysqld/mysqld.sock

production:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: robin_offline_production
  pool: 5
  username: root
  password:
  socket: /var/run/mysqld/mysqld.sock

and my migration file is just what run

rails g model events    

nothing special

develop.log

I just run

rake db:drop

and do the migration again, all goes well again

and rails db to goto the database and do whatever you want.
