Sublevel 1 is a very short one, being the smallest of the three sublevels. after going through the hole, you'll land in the area where the red-yellow-blue mark is. after this, attack the white bramble wall. you should then be able to fight 3 Dwarf Red Bulborbs and find Cherry.
Splash! you land in the water and think about it. you then figure out this level is just straight forward, but you need to grab those 2 presents first. you grab the one on the >, and get some Crackers. Then you grab the one on the <, and get a Baseball Bat. go to the next sublevel.
